Replacing motor in mobility scooter? Answered

Hey all,

I have a mobility scooter that I use for travel(caravaning among other). It's an Eloped Travel XL(40 kg or 88 lbs, 24V 22Ah battery), and I think it's only available in Sweden, but there are similar models all over the world.

My scooter has got a 180w, 24v motor on a transaxle with integrated gearbox. The more I use it, the more frustrated I get. It's slow, 4mph/7 km/h, but worse, it really struggles uphill and sometimes it feels like its gonna stop all together. I've changed the batteries, with no improvement. It's not overheating. My guess is that it's just to weak. It might be ok to use when going to the shop or on flat surfaces, but not on gravel or grass.

Anyway, I would like to replace the motor with a more powerful one, 350w or even 500w. The problem is that there isn't any compatible motors out there, so I'm guessing I'll have to replace the hole axle. I've been looking at these common China made electric motors that come in a range of sizes, have no idea about the quality though. Otherwise, maybe a powerful RC engine would work?

I have no idea really, where to begin. Money is a concern unfortunately, otherwise I could buy a new transaxle or even a new, better scooter.

Any ideas or help would be very appreciated! I'm quite handy but have never worked with these kind of parts before. How to pick the right sprockets, should I use chain or belt drive and so on.

I think you probably want to find a more powerful electric scooter or wheelchair motor if you can since it already has gear reduction.

You can go the route of getting a scooter motor, but you might have to do some serious modification. You also would have to worry about it possibly going to fast.
