I'll start by saying that I didn't actually buy my kit from kirbebike as I had it gifted to me, but this little motor is amazing. The install process is a piece of cake (unless your bottom bracket has seized, which mine had). This kit makes riding pretty much effortless, I've hit 31.8 mph on flat ground using only a 7 speed casette. The motor is quite and makes hills seem like your running over a mole hill. I'm writing this review on kirbebike as I'm a fan and supporter of Andys YouTube as well as his products, good quality stuff and Jason always provides great customer services.
Kit arrived on time,battery arrived later.This is my fourth e-bike kit,very impressed
With the power.I would appreciate more info on the controller connections,ie what is the shorting link for.
Excellent kit . Fitted perfectly on my bike and hits over 40 mph. One of the quitest kits i have ever bought. Very happy with the purchase.
Install was easier than I expected. The power is solid — great for daily commuting and weekend rides. I'm really satisfied so far.
The bike i built with the 4000w motor is great, easy to install and amazing performance. I emailed customer support for any questions and all theyve gave is help, i couldnt have bought a motor from a better place, theyve been quick to respond and very very helpful. Thank you kirbebike for this amazing kit!!!
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.
750watt Kit arrived in about 4 days battery came first and the kit arrived about 1.5 hours later,was well packed.kit quality is good and pretty straightforward to fit,the motor is quick and responsive and I managed a top speed of 34 mph so very impressed so far,the kit looks great on my bike:)
Unbelievable bit of kit. I use mine for off road and I'm very impressed with the power and the speed. Great buy and great fun.
