### ⭐ 1.0 out of 5 stars







  
  
    Not strong enough for its self
  

*by C***  on Reviewed in the United States on June 23, 2022*

No directions made it hard to get together right, if at all. When/if you could get motor started it throws the chain bending mounts in kit causing to readjust over and over, the sprockets on pedals didn't clear pedal arm so modified, sprockets were to thick for chain so ground them down till they did, and once they are on the bike it's nearly or even is to get back off the bike without bending one. DO NOT BUY

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    DO NOT BELIEVE ALL THE BAD REVIEWS
  

*by B***. on Reviewed in the United States on November 21, 2021*

i watched a lot of videos on how to put this together before i even purchased it. almost every video says the kits are junk, people cant seem to figure out how they go together or things just plain dont fit. upon reading most of the reviews for this kit i found the same thing. after purchasing i can tell you that its all b.s. everything went together perfectly, gears slid right over axle as did bearings. only problem i had is the crank doesnt work with my bike. that is my fault not the kits. i ordered the correct crank and am back in business. if you are on the fence, dont believe all the bad reviews. great kit, fits and works perfectly as should.

    Chain is garbage. Needs drilling. Nobody has done instructions.

    The shaft is made of butter. The 510 chain is stock so whatever. But the 1/2 x 1/8 chain has so much play in it, you could never keep it on the sprockets. The tensioner needs a bearing. Most of this kit will vibrate loose. The 9 washers spacing the plate will let you know when your time is near. Plus I had to drill out the holes on the backplate to allow my engine bolts thru. Took 3 months of tinkering! I build bikes in less than 5 hours....
