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.

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.

Faster on my bike than in my car.
I'm 52 carrying a bit of midlife weight and the doctor has told me to start looking after myself. So I bought a bike. I live two miles away from my workplace. Now as I work at a large vehicle manufacturing plant getting out of the car park is a nightmare. Not anymore. I decided to fit a kirbebike kit to my hybrid trek bike.Im home before most people have even got out of the car park. The kirbebike kit has honestly changed my life. I pedal as much as I can but when I need that little or big assistance it's there. FANTASTIC thankyou you have changed my life.
