MTB Conversion - 250W

Great kit, 700c for 29" tyre, relatively easy to install on new budget mountain bike. Needed a spacer washer on motor axle to clear fork on cable side, non-standard size (small OD, large ID) and had to manufacture it. Would have been helpful to have a couple included in the kit. The pedal assist sensor assembly was glued (JB Weld) to the bike's bottom bracket, but the sensor element protruded too far and fouled the magnet ring. Plastic sensor moulding fractured when removing it, so it had to be drilled and tapped, with corresponding clearance hole in the mounting bracket. Remounted using a spacer for clearance. Everything else seemed to go OK - you'll probably need more zip ties, get some decent thick ones. Thumb throttle not strictly legal in Australia but I fitted it anyway! (Display software can be modified to make it speed-limited/legit). Ordered a canvas waterproof pouch to house the controller and hide all the excess cable lengths - the supplied plastic enclosure is a bit too small. If fitting wheel to aluminium forks a torque arm is recommended, otherwise the dropouts will see the reaction-torque from the axle and might crack under the stress. BTW, You'll need a few specialised tools, e.g. crank puller. Kit is good value and I'd use it again. Makes for a very comfortable powered ride :-)

Good value for money

This kit has worked well for my bike. There are a few things that aren't the best (controller case has wrong screws so is unusable, plastic battery dock isn't the most secure, instructions are fairly basic), but given the price I'm fine with this. The bike runs well and the motor helps me up hills.

Electric experience

Bought my first kit about 2 months ago for my wife as she is awaiting a hip replacement opperation and can hardly walk let alone cycle,however by using the throttle control she can still get out in the fresh air and keep up with the group without having to pedal at all with a proven range on the flat of up to 40klm.
I was so impressed i recently converted my own bike so i can keep pace with her although i can go a lot further using pedal power with motor assist on hills when i need it.
Best thing since sliced bread thoroughly recommend converting your own bike at a fraction of the cost of purchasing a complete motorised push bike.
