Is it ok for a kid's bike to only have a front brake?

Small children usually do not have a grip strong enough to brake effectively with brake levers on the handle bars. Neither do they have enough coordination to modulate brakes. This means if they were ...

Don't - its dangerous ( Majority of braking force comes from front brakes) and in many countries illegal to ride on the road without 2 operational brakes. Likely you are using too much force and ...

How to enlarge dropout slots?

You can do it with files. The chrome does make the surface harder but it's not a big deal. This is usually seen when the fork was originally slotted to take a 5/16" axle. I'm not a Raleigh ...

Front wheel bearings change

Put the 3/16" bearings back in, even if you have to buy some fresh ones. Your quarter-inch bearings are not sitting in the bearing raceway right which is causing the too tight/loose problem. They ...

Front V-brake not working

A further thing to watch out for when following Argenti's (correct) advice: Check the end of the noodle holder very carefully. I've seen some old, cheap V brakes in which this was too soft and ...

What can cause the front wheel to lock up when going over a small bump?

This is inexplicable and we're missing some details. Any modern bike tyre will be 20mm wide as a bare minimum. Your electric scooter appears to have approximately 2" or 50mm tyres from the photos. ...

Should front fork sit directly on the axle thread?

That's how it should sit, yes. There is no significant force applied on the threads themselves, the wheel is held in place by the friction forces between locknuts and dropouts. Here are a couple of ...

Is it possible to change chainrings to bigger on Shimano FC-MT500-B2 (2x10, 36T-26T)?

Maybe It’s a 96mm BCD chainring so you might be able to purchase a compatible part e.g Shimano XT M782 40t 96mm 10-Speed. A third party 96mm ring will also be fine. You will be looking for 2x10 96BCD ...

Is it possible to change chainrings to bigger on Shimano FC-MT500-B2 (2x10, 36T-26T)?

You can add a few teeth, but not enough to make a significant difference. The photo shows that the front derailleur can be moved upwards by about 0.7cm, which would be enough to add 3 teeth. The ...

My front brakes got pulled off and they can't be put back on?

Second question first. It sounds like that "circle" is the cable stop. That needs to fit into a mating recess in your brake lever. Once you've done that, you should be able to fit the "...
