Bafang BBS-02 48volt 750watt Motor Assist - More power than the 500w version; this is a great option for those of you who are really into off-roading or for those who always seem to be climbing steep hills. The Bafang is a surprisingly quiet mid drive option that will add a lot of power to your ride. This is a great set up for those of you with a single chainring on your front crankset.
Falco 48V Lithium Battery (Charger + Holder Included) - The pack merely weighs 3.3 kg (7.2 lbs.) and it delivers 556Wh of energy (48V, 11.6Ah). The 48V battery pack has a number of primary as well as secondary protections. The packs use Lithium Ion Rechargeable battery cells from Panasonic.
