Stealth 1000W 29er Mountain Electric Bike

How It Works
Step 1
We supply an e-bike 70% built.
Step 2
You complete the remaining 30%. Instructions included.
Step 3
You save hundreds of pounds and feel like Tony Stark!
Build it to save hundreds
The last 30% of an e-bike assembly cannot be automated, making it the most costly for manufactures.
By completing it yourself, you get to save hundreds of pounds.
It's not a rocket.
But it feels close.
Beat any terrain like a badass.
Acceleration like no other.

1,500 Miles. Not a Single Problem.
Over 1,500 miles covered and not had a single problem. On the lowest setting it gets over 100 miles between charges. On level 2–3 the range is approx 60 miles. I would definitely recommend.

Reliable Since 2018
Bought a front wheel kit in 2018, no issues, totally reliable — battery was still good but bike was stolen. Will be getting another kit. Much cheaper than Swytch and Boost with similar quality.

All Parts Included. Running in Hours.
All parts required are provided, and all fitted and running in a few hours. Made a massive difference to my old mountain bike.

Controller Replaced Immediately
I bought a Beast which was working fine until there was no more electric power. After talking with Cyclotricity, they found out the controller was involved and replaced it immediately.

£300. Extremely Good Value.
I fitted the kit to my wife's bike very easily. The end result is a very nice electric upgrade that makes her journey to work much easier and safer. The bike has been working now for over a week tackling a rather nice hill every day.

Derestricted. Both Ways.
Conversion was straightforward and the derestrict codes were very helpful. It's good that I can swap from normal to derestricted and back as I only need it occasionally.
