I got this kit from Indiegogo as I really want an electric bike system that can be removed from normal bike easily. Rubbee drive has done a brilliant job and it doesn’t add much weight to my Brompton too. Really enjoy it so far!
The Rubbee X is an impressive device and concept but one that requires all 3 battery modules to really shine. The power and range are enough to satisfy, coupled with the convenience of compactness, ease of mounting and unmounting makes for an all-round well engineered and fun to use product.
