My Qile Duo lives again as a single speed!
Most of you may remember the fiasco the local bike shop created when I took my folder in for a simple inner tube replacement, which caused the rear axle to be ruined. Well I decided to to get my bike back on the road again without their help.
So I made the decision to convert my 5 speed setup to a single speed. I ordered a complete rear wheel through eBay, but it took longer than I anticipated because it was delievered to the wrong address! Luckily, the wheel was at a neighbor's home just across the street.
I started on this project this mid afternoon, and completed it in just over an hour and a half. Here is the result:
I took off the fenders, and kickstand. I wanted this to be a "no nonsense", beater or errand bike. The new wheel came with a 16 tooth cog. With the 46 tooth chain wheel, the final drive ratio is about 55 gear inches.
I did take the bike for a 2-3 mile ride, and I find that it pedals a "bit stiff". Maybe after the hub breaks in, it'll lossen up. I actually bought the chain at Walmart, and it was perfect. I didn't need to add or remove links.
Overall I am quite pleased, and it's more fun to ride. The coaster brake is way stronger than the band brake it replaced. With the front caliper, I have all the braking power I need.
By the way, in the last photo you can bearly see the brake arm, and the light gray object just over the arm is the plastic clip that holds on to the fork blade to help keep the bike together when folded.
It looks like this "old" bike is going to be around for a long time!
