Cycling - Recent Questions, Troubleshooting & Support

A 'Clunk' usually means something is loose or worn usually a bearing set. If you use it a lot it's worth doing some basic checks. These will feel silly but they work.
-Listen carefully as you pedal and try and work out exactly when in the pedal's circle the clunk happens. (Hard cycling? Gentle cycling?).
-Get someone else to ride it and watch and listen. Move around as you do this to try and locate the sound.
-Take a good look at the body and covers. Sometimes the noise is just a loose cover hitting a pedal.
-Hold the pedal crank with one hand with it pointing up to the ceiling and hold the pedal flat against the other hand. Try and push the pedal straight up and down with a bit of force, it should Not move. Repeats this for the other side.
-Hold the pedal crank with one hand with it pointing down to the floor. Place your other hand against the body of the trainer and pull and push the the crank towards you and away from you. It should Not move. Again repeat on the other side.
-Sit in front of the 'bike' and grip where the axle goes through the body of the bike on both sides. Push and pull hard like your steering a bike.
None of these should feel loose, clunky or noisy. Comment below when you've tried these and I'll try to help you more.

It could be that the chain needs tensioned, or if it is a coaster brake, the hub may need serviced. The noise could be coming from anywhere and your best bet is to have a qualified mechanic look at it.

Not possible to do over the Internet, and very unlikely to be any videos that can properly guide you. See if there's a "bike co-op" or "bike kitchen" near you and take it there or just pay a bike shop to assemble it.

The battery cover is no longer made since this bike was last built in the late 1980's. I would recommend giving the man a timer/watch. I do have one of these little black round batter covers, and would sell for $25. However, all it does is create a timer for the rider. He already can use the analog computer to see his mileage, load, and can re-set the lower mileage to zero every workout. All the battery cover will allow is for him to set a timer for how many minutes he wants to workout for. Or he can pust the start button to time his workout. (my email is

Can't answer your question without a more clear explanation. Apparently, you are talking about your entire wheel, not just the rim. The gear cluster in the rear is called a cassette, though the rotating bearing is called a freehub (one word). You need to explain what you mean by it "locks". Can you not pedal forward or can you not spin the pedals backward? It's important to place the chain on the correct cog when installing the wheel. Usually best to place the rear gear lever in the highest gear (smallest rear cog) when removing and installing the wheel.
