Knowing I cannot build my Geep in time for the Gathering I needed to look into something else to build I give you my 1989 Batricar mobility scooter This thing is built like a tank, none of your lightweight, fold in the boot nonsense, it weighs enough that 3 of us struggled to lift it into a pickup - the wheels and tyres are 14" diameter to give you some scale - it has indicators, headlights, tail lights and a disk brake Which brings me to step 2, I think it's man enough to take my second purchase 390cc and 13hp of Honda's finest 13hp is silly on a go kart by the way, let alone a mobility scooter ;p This will no doubt be a slow build, after all, I've got 8 months...

Brilliant. Are you sure that engine will produce enough power for your needs?

If you want to go mad I know of a Boeing 502-6 Gas Turbine engine in turbojet configuration with 250-260lbs thrust complete with starter, high pressure fuel pump, fuel metering device, igniters, intake screen, oil pump, tach generator and exhaust nozzle. The Batricar chassis looks to be sturdy enough

Tonight I set about tearing the poor thing apart. Something I actually sat and pondered over for a good 30 mins. I cant believe the thing worked after siting for so long. I never bought it as working, so had no issues with ripping it to bits, but for some reason, the fact that she was intact made me think hard about leaving her be. But then I looked across the garage and nearly 400cc gave me a cheeky wink and I was sold. 2 huge 75ah batteries, a rather large motor and all the speed control gubbins needed to go Looking a bit clearer in there now This is the sort of thing that made me think hard about taking it to bits. This is just the brake, a simple caliper would of sufficed, but this is operated by 2 separate cable systems. The hand brake and then if you yank back on the steering tiller the brake is also applied. Look how overkill it is, the metal is inches thick in places. Even so, it had to go. She weighs a hell of a lot less now. The brake operated directly onto the differential, hopefully I'll be able to replicate this using hydraulics as its a neat solution. I couldn't help throwing the engine in place to see what's what. Look at that, even mounted too far back - the electric motor mount is in the way - and too high it fits under the cowl. This thing is going to be stealthy. Though the head will have to poke out the cowl for cooling.

Did a bit more work the other night Cut all the old electric mounts and cap out which let me move the engine in front of the axle I roughly cut the cowl to allow the head to poke out for a bit of cooling I've ordered a few bits now, bearings, pulleys etc, but it's getting there...

As a user of a modern mobility scooter I want a Batricar as they look so well made

Bookmarked. Just make sure you don't burn your legs on the head when eventually driving it!

Clutch and jack shaft or CVT? Impressive looking differential thing, does it use rollers for planetary gears?

The problem I have is the power and the 25mm output shaft
Cvt's in that size are near £200
A clutch is £40 on eBay, but I worry about how good it would be for that
Looking at a belt tension clutch at the min
Or even better would be the 2:1 reduction box and wet clutch a lot of power washers and large generators have, but again, pricey...
The differential i believe is a ball bearing type like you see on R/C cars, though i haven't had it apart to check. I'll probably replace the axle anyways as i'd prefer a solid one

Could you just bang an electric motor on it and connect it straight to the generator? You could then have an on/off switch in place of a clutch? Like the way some trains work, although you may have to rip the regulator curse word out of the generator so the Volts can ramp up dependant on the engine speed which would give you speed control. although, is that really what you want? I can see the appeal of a mechanical drive,

I could of just kept it standard if I did that I think i'm gonna risk buying this clutch and seeing how it holds up I'll be gearing it for torques not speeds anyways, so in theory it should engage pretty quickly and not burn up Plus there might be wheelies

Plus there might be wheelies Then I'd suggest a roll bar or wheelie bars. The Batricar looks pretty heavy and a broken neck or back is sure to put a dampener on RR16

I got a new CVT gearbox with reduction drive off eBay for £10. It was intended for the generic Chinese engines found on MiniMoto, quads etc. The clutch is simply a centrifugal type that bolts to the engine output shaft. I'd look at those for adapting to your Honda engine. On ride-on mowers there often isn't a clutch but rather a loose drive belt that "slips" on the pulley. There is then an idler pulley that presses against the belt to tighten it when pedal operated and thus replaces a proper clutch. What about seeing if you can get a scrap scooter engine and use the clutch / CVT / reduction drive off that ? In fact a good running scooter engine with the wheel replaced with a drive sprocket might be worth considering as it's give you electric start and brake as well.

A cvt is nearer £200 for this engine :/
The engine was cheap and i'm a sucker for punishment so i'll stick with it.
Ordered a centrifugal clutch now, geared right it should last
