Torque sensor measures and multiplies your pedaling effort with 5 assist levels, helps you climb steep hills with ease!
Compact and well thought out conversion kits for bikes with 20", 26", 27.5" and 700C wheels with 10AH, 15AH, 17AH or 20AH battery.

Convert easily most bikes with 68mm bottom bracket to electric in record time!

Required skill level:

Although we take every step to make installation as easy and straightforward as possible, you still need to own and know how to use a digital multitester and to be able to:

  • - Remove and refit the cranks
  • - Remove and refit your brakes and tyres
  • - Remove and refit your freewheel or freehub
  • - Index your gears
Please use the web contact form or send your kit enquiries to kits@wooshbikes.co.uk - this is because it is not humanly possible for us to remember what was said on the phone after few conversations.
All prices include shipping to UK addresses.

Installation in 4 steps:

- replace the existing chainring with the new TS chainring.
- fit and connect the battery.
- fit and connect the LCD.
- Fit and connect the motor wheel.

Golden rules for installations:
- Cable from motor must exit downwards.
- Do not pull cable ties too tight.

What if I cannot fit the kit myself?
We will assist you in finding a local bike shop and liaise with the bike shop to carry out the work for you.
The average charge to fit our kits is around £100, you pay directly to the bike shop.
Kits are not the same as bikes, which are supplied as complete items needing little or no intervention by the customer.
If we cannot fix a kit under warranty to you, we will offer you a refund.
Please note that this will not be a full refund.
It will be based upon the condition and age of the kit, the number of miles it has done and whether any of its component parts are missing. Please refer to our sales terms and conditions for details.
In some cases, faults are caused by the way the kit has been installed or misused (eg derestricted, despite our warnings) rather than by a manufacturing mistake within the kit itself. In those cases, we cannot cover the cost of repairs under warranty.
