Electric Bikes and Big Ambitions – EVieBikes Land in Guernsey

EVieBikes recently landed in Guernsey, bringing the first ever dockless shared electric vehicles to the island. I got into contact with Gavin Breeze (founder and CEO of EVie), who kindly agreed to discuss with me where EVie came from, what the service means for the islands and their plans for the future!

Interview conducted on 2021/04/09.

A Brief History of EVie

According to Gavin, EVie bikes were “sort of all [his] fault”. After founding a software as a service (SaaS) payment company called DataCash and selling it to MasterCard, he found himself at a loose end. Deciding that he was “too young to sit around doing nothing” Gavin looked for his next project, which came shortly after hearing Phil Male (Chairman of JT) discuss a number of ideas he had for improving Jersey. Of the ideas put forth, Gavin decided that “as a private individual the only one [he] could have the […] remotest impact on was to try and move the dial towards the islands becoming all-electric islands” (moving away from internal combustion engine vehicles).

EVie’s first step towards this goal was to move into the shared vehicle hire space, which started with a launch of a couple of cars in Jersey in December 2019 and quickly expanded to a fleet of 10. It wouldn’t be long however until Covid-19 came along, meaning that “people didn’t want to get into a vehicle that somebody else had been [in] 10 minutes before”. Despite this setback, EVie had already sorted out a lot of the difficult parts (such as getting agreements from the Government of Jersey and figuring out logistics for running the service) and so managed to make it out the other side into the current landscape.

Following on from their electric car and van offering, the next step came about when Gavin “suddenly realised that, actually, launching a dockless shared bike fleet was going to be a hell of a lot easier”. EVieBikes were first made available in March 2020 in Jersey with an initial fleet of 140 bikes. Their first year of use was very positive, with 12,000 users taking 50,812 electric bike rides totalling a cumulative distance of 346,649km in 2020.

After realising that most EVieBike users were not bike owners themselves but might have an appetite for medium-term ownership EVie began their BlueBike service, a subscription scheme that allows for users to get full-time access to an electric bike without having to commit to purchasing one.

In early April 2021 EVie expanded into Guernsey with an initial set of 25 EVieBikes after talks with Deputy Lindsay De Sausmarez (President of the Committee for the Environment & Infrastructure) indicated that the island would be welcoming of such a platform.

The Target Markets of EVieBikes

Although EVieBikes can be used to get around as with any other bike, Gavin mentioned that they’re aiming for three main target markets:

  1. Tourists (when they’re allowed back in the islands)
  2. Commuters
  3. People running daytime errands

The parking situation in Guernsey was raised as a particularly large factor influencing this. After talking about the lengths that many Guernsey residents go to in order to secure a town parking space in the morning, Gavin mentioned that “if you do have to pop out at some time during the day you’re very reluctant to do it because you’re going to lose your car parking space! Whereas if you could just jump on a bike, keep your car parking space for when you want to go home in it and pop out and do your 10 minutes down the road, then why not?”.

Running a Responsible Dockless Bike Platform

Even after figuring out the logistics and operations required to bring EVie to the islands, operating the service is no mean feat. Phil Le Poidevin is EVie’s “man on the ground” where he is in charge of the Guernsey rollout and looking after the fleet, moving the bikes around to anticipate demand and to make sure that the bikes aren’t left scattered across the island.

Although Phil is indispensible in making sure that the bikes are where they can best be used, Gavin noted the importance of incentivising responsible behaviour from users as well: “There are a couple of ways in which we can do that. One is to try and encourage people to actually return their bike to a geolocated virtual bike rack. […] The other layer on top of that is what we call ‘yellow zones’. A ‘yellow zone’ is a demarked area where […] you simply cannot end your rental”.

These measures are intended to push users to utilise the service in a way that doesn’t negatively affect other islanders. “What we don’t want is people leaving bikes (especially in town) in stupid places. […] Having people park responsibly is incredibly important to us” said Gavin.

EVie are constantly making changes based on user feedback and they hope to apply the lessons they’ve learned from the “painful experiences […] in Jersey” to their Guernsey rollout of the service.

The Good and the Bad of Operating in the Channel Islands

Guernsey and Jersey both bring unique benefits and challenges to operating a platform such as EVie. On the positive side Gavin mentioned how range anxiety (the concern for electric vehicle users that they’ll not be able to make it to the next charging station with their current range) isn’t a problem for islanders as it might be in the UK, saying that “You’d really have to be driving around pretty hard to get through a battery in a day”.

On the negative side however is the dispersed nature of housing in the islands compared to a densely populated city in the UK since the bikes tend to migrate to lower traffic areas over time. Gavin went on to say “It’s very much easier to make money and make a fleet run efficiently if you’ve got high density areas where within that [area] you don’t really mind where the bikes are going to be left because you are pretty sure that somebody else is going to rent them from the same place. […] In Jersey and Guernsey, that’s not the case.”

The Future of EVie

Guernsey Expansion

For the moment EVie are focusing on the rollout of EVieBikes in Guernsey and the expansion of their local dockless fleet to 100 bikes, but the ship Ever Given getting stuck in the Suez Canal caused the second batch of 75 bikes to be delayed.

Further expansion of the services offered in Guernsey were discussed, but these are highly dependent on overall reception of the project as well as the political landscape in the island. Although the platform began in Jersey, Gavin mentioned that he had a “sneaking suspicion that one or two things are actually going to end up being launched in Guernsey before they are in Jersey because of the different attitude and different approach to transport”.

The Move to a New Platform

While the current EVieBikes and the platform they run on are both created by Freebike, EVie are planning on moving to a new bike supplier and separate software platform in the near future. Explaining the move, Gavin said “unlike in Jersey where the cars are on one stack and the bikes are on another stack, […] what will be being rolled out in the next week or so in Jersey is a new car app and then as soon as the new bikes arrive [they] will be hooked up onto the same platform and you’ll be able to see both the bike availability and the car availability from the same place”. Currently the electric car offering in Jersey is only available through the EVie app itself, with the bikes being accessibile separately from the Freebike app. This move will allow for a more consolidated and simpler view of what transport is available throughout the island.

The new platform will also allow EVie to easily add other mobility types they may release in the future (such as e-scooters or e-mopeds), grant them flexibility to support a more diverse set of electric cars and bikes and consolidate user membership into one place. Gavin went on to mention that the shared data “also allows us to be an awful lot cleverer in the fleet optimisation, so understanding where the heaviest points of traffic are and making sure that our fleet admin operators are slightly more agile and effective in putting bikes and cars where they’re most likely to be used”.

EVie’s electric cars in Jersey will be the first to migrate to the new platform with the electric bikes following after the set from the new supplier arrive in Jersey. The opposite approach was originally planned (with bikes migrating to the new platform first) but shipping delays forced EVie to reconsider their approach.

Battery Recharging

One of the ideas that EVie are looking into is that of an easier battery recharging/switching system which would allow for users to swap out batteries at recharge stations situated in key locations throughout the islands.

This could help alleviate some of the effort required from EVie to keep the batteries across the fleet charged while allowing for more user flexibility as even bikes with a low charge could still be utilised with a quick battery swap granting a larger/full range.

User Incentives

Although very much still in the concept phase, Gavin mentioned the possibility of introducing user incentives: “We might for instance post a bulletin saying that ‘bike number 67 is sitting at this crossroads and is out of station, anybody who brings it into town we’ll give them a free ride credit’. If somebody lives relatively close by and they were going to go into town anyway then why not pick up the bike and move it to somewhere that it’s more useful?”.

Such a system would benefit users who are willing to jump on any incentives offered whilst also saving EVie operators from having to relocate bikes that may otherwise be spread out a long distance from each other.

A Consolidated Payment System for Public/Shareable Transport

When discussing the future of the EVie platform itself, Gavin remarked “If you think about it, what we’re sitting on is a payment wallet. […] It would be very easy for us to use the QR code functionality of the app to [scan] a code sitting in a bus”. Rather than having different forms of public transport operating with entirely distinct payment systems, an EVie “wallet” could allow for a greater flexibility for islanders by giving them the option of using the EVie system to pay for all kinds of transport, streamlining the process if they wanted to (for example) catch a bus into town and then rent a bike to get closer to their final destination.

Park and Ride Scheme

In-town parking has a cost associated with it in Jersey, but this cost often depends on its location (mainly how close to the centre of town it is). EVie are looking to help with this by turning the furthest away locations into “Park and Ride” stations, allowing for people to park in a cheaper location and making the rest of their journey on bike. “With a bit of luck it will encourage more people to use those parking places for their cars rather than fighting for one in town, driving [round] in circles looking for a free space” Gavin said.


Personally, I’m really excited to see what EVie will bring to the islands over the next few years. I’ve already tried out the service myself and will be writing a separate post about that soon (so keep an eye out for that!) but I can definitely see myself using it in the future.

A huge thank you to Gavin for his time and willingness to answer all of my questions. Our half hour interview quickly spiralled out to last over an hour and I’m sure we could have both continued talking for far longer if we had the time!

Multi-Factor Authentication with Password and Private Key File in SSH.NET

If you want to use SSH.NET to connect to an SFTP server that requires both a password and a private key file, you’ll be happy to know that it is well supported! Unfortunately (and similar to my previous SSH.NET post about modifying the Host Key Algorithm) the documentation doesn’t really make it clear how to do this.

As an example, let’s grab the code sample from the SSH.NET documentation on multi-factor authentication. At time of writing it looks as follows:

var connectionInfo = new ConnectionInfo("sftp.foo.com",
    new PasswordAuthenticationMethod("guest", "pwd"),
    new PrivateKeyAuthenticationMethod("rsa.key"));

using (var client = new SftpClient(connectionInfo))

If you modify the server address, username and password and then run it you’ll quickly hit a brick wall in the shape of this error message:

Renci.SshNet.Common.SshAuthenticationException: Permission denied (publickey).

The first issue that we’re running into is that we’re not actually specifying the private key details anywhere! Let’s change that (I’ve also swapped the literal strings out for some variables):

string _privateKeyPath = "";
string _privateKeyPassPhrase = "";
string _host = "";
string _username = "";
string _password = "";

var keyFile = new PrivateKeyFile(_privateKeyPath, _privateKeyPassPhrase);
var keyFiles = new[] { keyFile };

var connectionInfo = new ConnectionInfo(_host, _username,
    new PasswordAuthenticationMethod(_username, _password),
    new PrivateKeyAuthenticationMethod("rsa.key", keyFiles));

using (var client = new SftpClient(connectionInfo))

Now if you run this you’ll get a new error (#ProgressIsProgress), this time telling you that you’re not allowed to change username:

Renci.SshNet.Common.SshConnectionException: The connection was closed by the server: Change of username or service not allowed: (<USERNAME>,ssh-connection) -> (rsa.key,ssh-connection) (ProtocolError).

Now when I first ran into this error and threw it into Google I got very few results; looks like we’re treading new ground!

The fix for this is actually really simple; the constructor for PrivateKeyAuthenticationMethod takes a username as the first parameter! For some reason this is set to “rsa.key” in the official documentation rather than “guest” which they use as the username placeholder on the two lines above, so when I first looked into this issue I wrongfully assumed that it was a string specifying what type of private key was being consumed!

The only change we need to make to the previous example is to swap in the _username variable (or a literal string of the username if you prefer) for the first parameter of the PrivateKeyAuthenticationMethod constructor.

string _privateKeyPath = "";
string _privateKeyPassPhrase = "";
string _host = "";
string _username = "";
string _password = "";

var keyFile = new PrivateKeyFile(_privateKeyPath, _privateKeyPassPhrase);
var keyFiles = new[] { keyFile };

var connectionInfo = new ConnectionInfo(_host,
    new PasswordAuthenticationMethod(_username, _password),
    new PrivateKeyAuthenticationMethod(_username, keyFiles));

using (var client = new SftpClient(connectionInfo))

Run it now, and you should connect successfully!

Regular Expression Tips for People That Hate Regular Expressions

A screenshot of a code editor. There are three lines, setting the variables "isCustomerNumber", "isProductNumber" and "isTransactionNumber" based on whether a series of regular expression (regex) matches succeed

I’ve been writing regular expressions (regex) for years and would consider myself pretty good at them by now (I decline to provide references). The problem is that although it’s common to see regex as cryptic and painfully terse (which are not invalid points), they remain one of the best ways to handle complex pattern matching and as such you’ll probably run into them at least a few times in your career.

Even if you really despise writing regular expressions, here are some tips that will help to make that process as painless as possible!

Epson ET-2711/ET-2710 Series Printer Wireless Setup Made Easy

If you want to just get to the good stuff, scroll down to the “Setup” section.

My wife and I finally got a new printer to replace the old one that has pretty much given up the ghost and refuses to print anymore (often considered an important feature for devices like this).

We settled on an Epson ET-2711 in large part because of the ink tank that should (hopefully) do away with the constant stream of expensive cartridges in favour of some cheaper-per-page ink bottles. I was excited to get it out and start setting it up (in part because we’re in another lockdown and what else is there to do right now)!

Imagine my frustration, dear reader, when I found out that the whole wireless setup process for this printer is terrible if you follow the official instructions. I genuinely spent a couple of hours bouncing between the Android app (which gave me a very helpful message telling me “Communication error”, to check the printer is on and not much else), the included software for Windows (which was just as helpful), the printed documentation in the box and the website, all to no avail.

You cannot convince me that this is a helpful error message

The good news is that I finally figured out how to get it working. The even better news for you at home is that I’ve gone through the process three times so that I could document all of the steps to get this working properly!

Migrating from KeePass to 1Password

An image of the KeePass and 1Password logos, with an arrow pointing from KeePass to the stylised "o" in 1Password

I’ve been using KeePass for my password management needs since early 2014, but I recently decided that I wanted to move to something a bit more substantial. KeePass is an excellent (open source!) piece of software, but since it stores passwords in a single database file the only way that I could really sync it between multiple computers and my phone was to store that file… in Dropbox.

Yeah, as you can imagine that’s not a great solution.

Anyway, I wanted to move over to 1Password but when I tried searching for “Migrate KeePass to 1Password” I kept seeing references to 3rd party scripts I’d need to use to convert my exported data (no thanks) or that it would require a bunch of manual data entry. After giving it a go though, I can tell you it was actually ridiculously easy and straightforward and didn’t require any external tools or scripts! As such, I decided to put together this step-by-step tutorial for migrating your data from KeePass to 1Password!

So You Want to Run Azure Functions Using .NET 5

I’ve spent the last couple of evenings trying to get a set of Azure Functions migrated from .NET Core 3.1 to .NET 5 so that I can play around with some of the nice new syntax options, nullable contexts and the like. Since .NET 5 has officially been released, it would be justifiable to believe that it would be well supported across the core Microsoft product catalogue, such as in… say… Azure Functions?

Ha! You’re a funny one.

There Is No Such Thing as a New Idea, and That’s Ok!

A lightbulb laying on a chalkboard, with a thought bubble drawn around it in chalk

Mark Twain once wrote that “there is no such thing as a new idea” and quite frankly I’m starting to agree with him.

I’ve spent the last month or so actively trying to come up with some ideas for projects/ blog posts to work on that would be interesting and useful. The issue I’ve run into is that almost every time I come up with something, I give it a quick search only to find out that it’s already been done (sometimes many times over). That means another idea goes on the pile to be abandoned since “there’s no point in doing it anymore I guess”.

Well that’s not a fun feeling to have.

Changing Host Key Algorithm in SSH.NET

I’ve used SSH.NET a lot over the years to send and receive files using SFTP and it’s a very flexible and practical library, but the documentation can be a bit thin on the ground when you’re looking to use some of the more esoteric features it has.

As an example, I recently ran into an issue where I was connecting to a remote server and the host fingerprint I was receiving through SSH.NET didn’t match the one that I expected to see (and could see in WinSCP). After verifying that I was using the same connection settings on both and more than a little spelunking through the SSH.NET source code I found that by default the host key algorithms used by the stable release of SSH.NET that I was on (2016.1.0) are RSA and DSA, while WinSCP uses Ed25519. For my purposes I needed to use Ed25519 in SSH.NET as well even though the SFTP host also supported these other algorithms.

SoundFloored: Open Source Soundboard Pedal (Part 4 – Final Implementation)

The top of the SoundFloored pedal. It is held together by various cross-head bolts and has six footswitches embedded in the top, with four along the close long edge and two along the far long edge (with a screen embedded in the lid between them)

This is the fourth and final post in a series about designing and creating SoundFloored, an open source soundboard pedal! Check out the other posts in the series:

So SoundFloored is now working just like I wanted it to with buttons and a screen, but the current build isn’t exactly what I would call robust. As such, the final part of the build involves moving what I’ve built so far into a more permanent home, one that can withstand the rigours of live performance and is far more practical to move around.

Building the Box


Based on some preliminary research on the minimum usable distance between footswitches, I decided to keep them 7cm apart from each other to ensure good clearance. I also thought to leave a 3.5cm gap between the switches and the edge of the pedal since I didn’t need as large of a gap but still wanted the numbers to map out in a simple way.

Since there were going to be four footswitches across the length of the pedal, it would need to be 28cm long (3 x 7cm for the gaps between each switch, plus 2 x 3.5cm for the gaps between the outer switches and the edge). Similar maths for the two footswitches going across the width of the pedal gives us 14cm (7cm for the gap plus 2 x 3.5cm for the edges).

I wanted to find something with these dimensions (or near enough) that I could use to house everything, so I started by looking at “project boxes” (plastic boxes designed for maker projects like this). Unfortunately, the largest project box I could easily order was barely half the size that I needed and I wasn’t interested in putting in a custom order to create one. The only option left at this point was to build something myself!

I figured that wood would be the best material for this project; although not the traditional material for a pedal, I could make it pretty much whatever size I wanted, it’s readily available, cheap and I already have some basic experience in woodworking.

At this point even though I had the dimensions I wanted to get a better perspective of how big the pedal was going to be before I started building anything. Mediocre arts and crafts to the rescue!

SoundFloored: Open Source Soundboard Pedal (Part 3 – Breadboard Implementation)

A Raspberry Pi connected to a breadboard with various wires. The breadboard has a screen on it that says "Memes" on the first row and "RS: STOP" on the second

This is the third post in a series about designing and creating SoundFloored, an open source soundboard pedal! Check out the other posts in the series:

So this project has really been gaining some steam! I’ve figured out the design and managed to get a software implementation with two separate interfaces. Now though, I’m entering uncharted territory; the world of hardware electronics.

Now I say uncharted territory, but I’d be remiss if I didn’t mention that I’ve previously watched a Pluralsight course called something like “Introduction to Electronics” or “Electronics Fundamentals”, although it’s also worth mentioning that I remember approximately 5% of the content. Actually, one of the few things I did remember was how a breadboard works, which is a place to start at least!


So although I’ve owned a number of Raspberry Pis over the years and have a lot of HATs/pHATs to go with them, I’ve never ventured far enough into the hardware electronics side of things to have bought any components. As such, I ordered a pretty generic looking “Electronics Fun Kit” that had pretty much everything I might need for this project; a breadboard, wires (especially wires that I could use to connect the Pi directly to the breadboard), buttons, LEDs, resistors etc. I’m sure there are higher quality components out there, but since this is all for prototyping I decided that in this case cheap and cheerful was what I was looking for.

An ELEGOO Electronics Fun Kit, which is comprised of a cardboard box and various electronics components such as wires, buttons, capacitors, resistors etc.
