Review on Electric Bike Conversion Kit - Voilamart 26" Rear Wheel, 36V 500W Motor, Intelligent Controller And PAS System For Road Bikes by Patrick Lets

This motor exceeded my expectations. There are some big caveats in my recommendation here. This motor is smooth and quiet and can get you over the hills in great form with very little help from the rider. I mounted this kit on a homemade crank forward bike I built a while back and am using a 36v battery made up of 3 12a.h. S.l.a. Batteries. The whole bike weighs about 90 lbs but it doesn’t peddle too bad even without the motor running. I’ve only hooked up the twist grip throttle.no p.a.s. it will do a good 15 miles with minimal help from me and will hit 25 m.p.h. On level ground. I never expected to get so far on a charge running on $75 worth of batteries. With that said, there are serious cautions to taking on this project. The axle is very wide on this motor and a rear triangle spread of 140mm was required before I could get the wheel in place. I used a small automotive scissors jack to spread the triangle.something I’ve done numerous times.it works well on STEEL frames if you work carefully, trying a little and measuring progress before adding more force. The rim will need a good cloth rim tape before mounting a tire and a tube with longer valve stem would be best. The tire that was included was not one I’d try to use. I added a little lock tight to each spoke nipple after noting that they were well tensioned. I swapped the 7 speed cluster for a 5 speed as the 7th sprocket was too close to my right dropout and using a 5 speed cluster allowed a better chain line (I only seem to use the top 3gears anyway). be sure to get a freewheel removal tool before installation of the freewheel as you may need to add spacers between the freewheel and motor body. The freewheel tool won’t work unless the hole is at least 15 mm dia. to fit over the fat axle (a machine shop can drill the too.it’s tough but not super hard). Once you get the wheel and cluster complete the rest of installation is pretty straightforward.wires are color coded.I didn’t try to install the p.a,s. and did not connect the blue speed limiter wires together, the installation book is pretty well useless but everything works great once connected. I did run the 36v line to an in-line 20 amp automobile fuse and then through a standard 110v light switch before the red wire connected to the controller. I gave this 5 stars for value ($154 USd) and exceeding my expectation of performance with the caution that some effort is required to make it fit.
