  • I think you are on the right track, because the relationship between the driving sprocket and driven sprocket doesn't change like on a conventional motorcycle. But the quality of manufacture is a little inconsistent, so it wouldn't surprise me to find your suspicion is correct.

I've seen mention of aftermarket motor controllers and DIY throttle stops. The bike can be a handful for my little guy. Any new info here is appreciated.
  • Afraid I can't help you here -- my experience has been with the 24V bikes.

The 36V bike appears to have (3x) 12V/10 AHr batts in series and a 1.8 A charger. 12 hours seems like a punishingly long charge. Is it really necessary to equalize the crap out of these things three times right out of the box?
  • Big drawback with the lead/acid batteries. Several of our dads swapped batteries for newer tech. I expect at least one of them will be around soon, and has already posted at Trials Central.

  • There are (or were) accessory rear shocks and springs available from OSET and in the mountain bike markets. No quick fix for the forks, though. For our bikes I never found a soft enough setting for good compliance, and the lack of front adjustability made it a moot point anyway. No balanced settings to be had. The TC community may well have hit upon some solutions.

  • I ran 15-18 psi with constant vigilance for the tire slipping on the rim and ripping the valve stem out. I also took to running the heaviest thorn-proof tubes with slime. One running gear swap I saw incorporated a rimlock on the rear, which allowed lower tire pressure.

I know this is an uphill battle in the states, but our sport will eventually die or be legislated away (and then die) if we don't get the little ones involved.
Lewisport has handled OSETs in the past. Don't know their current status.
