Kirbe bike 52v 2000w Ebike kit

I ordered my Kirbe E bike kit my battery arrived 6 days later and my E bike kit arrived after 8 days and we're packed extremely well.The kit was easy to fit I had to take a small amount of the dropouts with my Dremel for the axle to fit. The electric motor is very powerful and extremely quite.I am very happy with my Kirbe bike 52v 200w Ebike kit

Faster than 5kW

Bought this as an entry into e-moto, just built a 5000w kit from another supplier, and its 5-10mph slower, would definitely recommend kirbebike's kit, never had an issue.

My Super73 is now super powerful :)

Fitted the extreme motor fat tire 20x4 kit to my Super73zx and it's bloody marvellous' so fast and so much fun to be had' Super73 use there own unique torque arms so some modification is needed but the dropouts length of 190mm is the correct size and 175mm is to small so don't make that mistake if considering other kits.

Great kit and delivery was within a week with full tracking provided.
