Thanks gwhy I'm fairly methodical about checking and adjusting chain tension before each ride (and he rides 3-4 times a week). I don't think the motors are designed for the type of terrain they're used on, not enough waterproofing. Having said that last time I rebuilt the Oset motor I put an oil seal on the sprocket shaft, and that seemed to help. I'll do the same with the Gas Gas motor this time. I hear what you say about carrying spares, but you I've never had to do that with a petrol bike, no need, they don't need it. Rebuild it every year or 2, but no need for in season rebuilds. Last trial I was at there were about 3 OSets all with noisy motor bearings. I'm not sure why you think I'm not interested in performance. There's nothing special about the 36v motor. I hear the new 48v is bespoke, hope it holds up better.

Hi Mooky That's because it's made under licence by Mecatecno for Gas Gas. I was having problems with Oset parts, first no springs/shocks, then no front mudguards so figured part availability couldn't be any worse. Gas Gas and Mecatecno UK have stock of mudguards etc, and that was my main requirement, as the electrics on these things are basically the same apart from the control unit. Incidentally you can get both 30 amp and 40amp controllers for the MecaGas. So I can get the motors from Oset, Gas, Mec or cheaper still by just Googling. And this was my major concern, as we run the Oset for 12 months and had 3 bearings and a motor failure. A few months in and the bearing is nosiy on this bike, but thankfully MecaGas come with 12 months warranty. Having said that I have just found one really good difference between Oset and MecaGas, and that's the motor is dropped out by 3 bolts, no need to remove and split swingarm, which is great given how much these fail when they're used properly. Oset should take note of this. So, so far, only a good experience, and his results have improved as well, which of course could just be coincidence. Can't wait to move to a petrol bike though, find these electric bikes more like toys (nice toys!) with less reliability and more maintenance required. Once he's old/big enough enough I suspect the electric bike will be confined to practice only.

I've been following trials central for a while but have only just joined the forums, which have been of great use over the past couple of years. We have been using Oset's, first a 12 inch and for the last 12 months a 16 inch 36 volt bike for my 5 year old. The Oset was second hand when we got it and we just decided to buy him a new bike now he's been competing for a few months. After looking at Oset and Gas Gas versions we opted for the Gas Gas, which was quite a bit cheaper at £900 (36 volt). I was sceptical as everybody else seems to favour the Oset! We have been running the Gas Gas for a few weeks now and all so far is well with it. If anybody else is thinking of changing I would have a look at one, as they appear to be a little better thougth out than the Oset, and just a bit more modern. The plus point so far vs Oset are as follows: Power delivery seems smoother and therefore has more traction (the Oset has very aggressive delivery) The controls such as charging plug, key and speed restrictor are much more accessible/sensibly placed It doesn't have those stupid MTB forks which spin 360 degrees, therefore it has a steering lock, which is much better and safer for kids The electronics are better protected being held between the frame with a nice plastic cover which keeps the water and mud away from them The swingarm has more shock positions and I thinks is 1 piece rather than 2 (haven't taken it off yet!) The batteries are better kept in place with individual rubber covers It's more modern looking, and of course Gas Gas have made it more visually pleasing (not that important for me, but for the boy he now has the same as Raga!) Small things like the use of hex bolts vs philips screws The bad points: The standard tyres are only 2.4 wide, which is fine for the front, but not for a rear The standard mechanical disc brakes are not great (although have upgraded to hydraulics as this is what he was used to) If anyone has any questions, feel free to ask!
