A bike retrofitted with the Gruber Assist - you wouldn't know it was there would you?
The Gruber Assist kit
There’s a few reasons why cycling has remained a popular form of transport for over a century. It’s cheap, keeps you fit, is environmentally friendly and it’s fun - usually. Unfortunately it can get a little less fun when you hit a steep hill or have neglected your fitness for a while. This is where electric assist devices such as the Gruber Assist can come in handy. It still lets you do most of the work, but helps to make the job that little bit easier. Whereas electric bikes such as the E+, the eneloop and the Gocycle require the purchase of a complete bike to get some electric assistance, the Gruber Assist can be retrofitted to practically any bicycle provided it has a seat tube with an inner diameter of 31.6mm.
