Kids bikes and gears…
Is he also waiting too late to change down
Dunno, he just doesn’t have the strength in his hand/arm to move the shifter down (going up, the spring tension pulls it). I put the bike in the workstand to show him how it all works. He seemed to understand it, but even with me turning the pedals, he just couldn’t change gear.

My 5-year old son has just got an Islabike Beinn20 (small) for his birthday. Its secondhand, but in immaculate condition.
I’m trying to dissuade him from changing gears too much to start with but he does sometimes. Sometimes by accident, sometimes because he’s realised he can go faster if he changes up.
The problem is, he can’t change down, leaving him a bit stuck when he stops. I don’t know if its the Sram 1:1 pull ratio, or what, but it is actually quite hard changing down. I’ve checked and the cables are free and easy, as is the gripshifter. It seems that the spring on the X4 mech is just very stiff. (mech bushings seem fine too)
Can it be replaced with a weaker one? Are other gear systems more suitable for little hands and arms? I can’t believe Islabikes don’t have the best one for kids though…Posted 4 years agoflatpatMember
Ha! My 7yo is now riding around the trails in 1st gear, so that he never gets caught out by hills. It is, however, preferable to the first habit he picked up on a geared bike of “turning it up to 6” at every opportunity and then moaning on every slight rise. We’ll get there eventually…Posted 4 years ago
So, further investigation has shown that its the section of cable outer nearest to the mech that is causing the sticking issues. Pulled the cable out so i can give it a good clean, but the end is kinked from the clamp bolt and it won’t go back in. No problem, I think, I’ll just fit a new cable from my stock of spares.
HOW CHUFFING HARD IS IT FIT A CABLE TO A SRAM 3.0 COMP SHIFTER?
Very, it seems.
Bike is now singlesppeeded whilst I source a (better) replacement shifter. Either Sram X3 from CRC, or old-school thumbshifter with an old XT mech I’ve got.Posted 4 years ago
Official response from Islabike is that the cable can be replaced.
According to sram, its easy:
4. Push cable up/out of the shifter and discard.
5. Feed the new cable through the cable entry and out the barrel adjuster.
this looks more useful though:
I’ll have another go this evening. If that fails, I’ll get an X4 shifter from CRC.Posted 4 years agoPTRMember
Gripshifts and cable changes, mmmmm…Posted 4 years ago
I ended up fitting a new gripshift, they come with the cable fitted. The end was frayed after the end cap fell off, I thought it would be a ten minute job to fit a new cable just to tidy it up. I was very wrong.
Another reason to go for triggers.
