The E-FATI range are equipped with BAFANG 48V 500W rear wheel motors with Samsung 48V 17,4Ah 835Wh If you intend to use your E-FATI on short trips and reasonable slopes, if you like dynamic driving for urban use, you can opt for an engine in the E-FATI rear wheel hub. This engine is the most nervous and reactive because it is directly connected to the rear transmission, and accelerates without going through the crank, the pinion and the chain. Which is highly appreciated by those who love dynamic driving. The E-FATI engine, built into the hub of the rear wheel, is virtually invisible. Many models, even high-end, are based on this engine.
