Motorized Bicycle Spring Loaded Chain Tensioner

I was having a problem keeping my chain taut, and was very unhappy with the stock chain, so off to Tractor Supply for some #41 chain. Got the chain and got to browsing and also picked up a really sweet ball bearing, rubeer coated chain trensioner, AND spring, it is sold seperatly. After mounting the chain I took some 3/8 althread rod, heated it up and bent it into a U shape to fit around seatpost. I cut a strip of metal ( out of stock tensioner mount) to secure allthread. Then I just mounted the spring tensioner to the end of the allthread, the ID of the tensioner seems to be a good fit on 3/8" rod. Then a little adjustment and done. Spent $40. on everything including new chain. I have put a couple of miles on it an it is a lot quieter, and very smooth...

And the spring tensioner was less than $15. with spring at tractor supply company.


I had someone ask me about the parts I used. I looked on TCS website and they do not show them. It looks like they carry them as accessories for their line of mini bikes "Baja Motorsports". Anyone interested the part numbers are as follows:
#165-063 Chain Tensioner with roller.
#165-280 Chain Tensioner Spring...
