The Italian company BOTTECCHIA produces a complete range of e-bikes which includes e-road, e-city, and e-folding bikes. Bottecchia e-bikes are motored by the Bottecchia ETR3 drive system consisting of a motor unit, display, control unit, battery, etc. The ETR3 (90Nm) engine offers plenty of power and assistance and it is perfectly suited for e-MTB usage since it can tackle the most difficult trails without any problems. The most gentle version of the ETR3 is mounted on trekking and city bikes. 

There are not many tuning systems to derestrict these engines however, the SpeedFun here does extremely well since it has proved to be a reliable tuning for the BOTTECCHIA ETR3 engines.
