Friction drive conversion kit
Eswytch VoltKit
Turn your existing bike into a stealth electric commuter in minutes. No wiring nightmares, no frame drilling, no £1,500 e-bike bill.
Turn the bike you love into the e-bike you wish you had.
The Voltkit is an electric motor powered friction-drive unit that locks onto your existing bike and gives you assistance in minutes. No workshop visits, no wiring jungle, no frame drilling. Clip it on, power up, and your "normal" bike suddenly feels like a premium e-commuter.
The kit is lightweight, compact and easy to remove, so you can switch between E-Bike and Standard whenever you want. It is built for real-world riding: hills, headwinds, stop–start city traffic and those "late for work" mornings.
Why riders are switching:
- Keep the bike you already like – just add power
- Installs in minutes with basic tools (no mechanic needed)
- Stealth look – no huge hub motor or bulky frame pack
- Ideal for commuting, uni, delivery work or weekend rides
- Designed with real-world riding and regulations in mind
Instead of dropping thousands on a new e-bike, ESWYTCH upgrades what you already own. Same frame, same fit, same style — just smarter, faster, and way more fun to ride.

My 25-minute uphill slog to work is now basically a glide. Kept my old bike, just feels like it levelled up. Install was way easier than I expected.
I use it on Sundays with the kids and pop it off during the week. Didn’t want a full e-bike, this kit is the sweet spot.
Helps a lot on long shifts. Range is solid in low/mid assist modes. Took me about 15 minutes to dial in the mounting the first time.
Great Purchase worth the money in my opinion. Need to have more of a range and stronger models in the future.
I take my bike to work and back and this is perfect. I sweat a lot less so Its nice not stinking when I get to work. I get in a little earlier now as well :)
Cute little thing, I hate the hills I have to go over on the way to work everyday and this helps me a lot. I reccomend for anyone that struggles with uphill journeys on their bikes.
I've tested different ways of balancing the different modes to get more range out of things. You just have to be smart with it.
I'm a delivery rider and this is a lifesaver. I'm a college student so I don't have 2k spare.
Great Product!
This is an everyday upgrade, I take it to school everyday and put it in my bag. It weighs less than my water bottle and is easy to carry around in my bag.
I never used to cycle but after getting this I've started using it a lot more. I take the bike to the shops and work sometimes now. This makes it so much fun, absolutely love it!
The thing looks so cool, it's like I'm in the future.
Killing the mountains with this. I go cycling with a bunch of friends and this always keeps me ahead of them.
I usually have to run errands for work and this is perfect.
Great little toy, I have bought myself one now and have the perfect Christmas gift for my wife. I'm excited for her to ride with me. I've got her a new bike and the Volkit.
Great for my gym journey as it prevents me from being exhausted by the time I get to the gym. It makes pedalling so much easier and effortless.
This makes my life so much easier. I'm a delivery driver and my legs are thanking me for this.
It arrived in good condition and shipping was quick.
I've always been a cycling fanatic and never wanted to switch to full electric because it's too expensive and I love my bike too much. So this was a nice middle point.
I use this pretty much everyday now, best gadget ever.
I use the bike for most small journeys and the Volkit has made the journeys smaller lol. I was curious and too tempted not to buy and I'm happier than I thought I would be. No complaints!
