- Kids BMX / u-brake
Jnr’s got a new bike which has a u-brake at the back. It did go through a gyro but he’s 7 and would never use it so it’s just a straight cable to the straddle and u brake. Only prob is it’s really hard to pull the brake lever to get the brake on. It’s fine for an adult but for him it’s tough so he tends to jump down off the bike to stop it. Not ideal in an emergency situation! Previous bike had a pedal back rear brake and a front lever which was fine. Just this one I can’t seem to make it “easier” for him to pull. It’s been 30 + years since I faffed with BMX’s. It’s a new cable, and new lever. Any ideas?Posted 1 year agoStevet1Member
Spring tension is usually set in a similar way to canti’s – theres a helical spring in the arm, you set the tension by pushing the arms away from the rim and nipping up the bolt that holds them on the stud. The further away they are the greater the spring tension/force required to get the brake to hit the rim. Unless its an Odyssey Springfield brake with the spring across the tops of the arms, think that one can’t be adjusted.Posted 1 year agocoomberMember
Same issue here and struggling also to find brake levers that are small. Have some Hoy kids v brake levers on his mountain bike, which have really small reach, but the u brake levers are a fair way away from the bars.
Separate issue but if you can find levers that are smaller, might make the issue easier? And if you do find levers let me know what/where!Posted 1 year agohollyboniMember
I think U brakes require levers with more pull like canti and road stuff. If there is a V-brake lever on right now that’s why it’s hard the pull. Check if it’s V or canti.
If the thingy where the cable attaches is farther from the pivot point it’s for a V-brake, if it’s pretty close it’s a canti lever.
Sort of like this:
Tektro makes small levers for kids for both V and canti brakes.Posted 1 year ago
