Interesting electric motor--fits Hondas...

I stumbled across a Chinese electric motor with a four speed transmission that will bolt into any Honda 50/70/pushrod 90 or similar clone (or an OHC 90 with the Dr. ATV adapter kit). It appears to basically be a set of standard horizontal engine cases without a hole for the cylinder to fit into and instead has an electric motor where the stator normally goes.

Throttle adapter for ATV, motorcycle, electric motorcycle

$599 to your door, or so the website says. Might be an interesting start to build an electric Cub.

Shoulda bolted it where the cylinder was...that thing sticks out wayy too much. Must interfere with the gear shifter. Could use more power. Otherwise good idea.

It sticking out may or may not get in the way... the nice thing is it eliminates a power transfer (belt, chain, or gears) in favor of direct drive to the gearbox.


I like it a lot but I don't know if I like it $600 worth. The gassers are much cheaper.

P.S. Just saw the vid in the link. What is that terrible sound? It sounds like something that won't last long.

If it is both a 4500w motor and the gearbox seems like a good value. The noise it makes is a bit scary. Maybe they did something wrong, and sometimes a microphone does pick up that electric wine well, it's the way it sounds like it has a few marbles in there as well.

I also think the layout is necessary for it to fit into the Trail and Cub fames.

Yeah, mounting the motor where the cylinder/head would have gone would've required a right-angle change of direction of the drive. If you think it's loud now imagine what it would be like with another set of gears (which would also eat power).

I'm thinking they could have cut away the engine cases and moved the motor inboard with a shorter coupling to tie it to the primary drive. Looking at the electric motor by itself and it's current location I'm thinking they had to use the standard main bearings to support a long coupling with oil splashing about in there to lubricate them.

It wouldn't be terribly difficult for a clever builder to roll something like this together out of a standard Honda 50/70/clone motor. A plate of aluminum bolted over the cylinder hole, a simple coupling made on a lathe, figure out a mount for the motor and away you go.

It would fit where the cylider head is with no issues; you'd still be shorter than a regular OHC cylinder, though a bit wider; the front of the engine hangs out in open space, so the extra width wouldn't mattter, and would still be less than the width of the case.

No reason to turn it 90 degrees, either. 1:1 gears are 99% efficient, unless run at right angles. A cogged belt would be quieter than gears, and just as efficient.

There's no clutch lever, so it probably use a centrifugal clutch, like most of the semi-automatics. That will eat up more efficiency than anything else.

Didn't notice the noise the first time; watched it without sound. These engines have a lot of internal noises coming out of them...I tended to assume it was due to things like the timing chain, but perhaps not...you would barely notice them on a gas engine, with the usual putt-putt going on.

As to just taking the cylinder and piston/rod off...the crank would now be really otu of balance, so you'd have vibration issues to deal with.

Maybe I didn't make myself clear. I'm thinking doing away with the crankshaft altogether and replace it with a straight shaft that would tie the primary drive/clutch to the electric motor. This shaft would be supported by the stock main bearings. Nothing to get out of balance here!!

Like I said nothing the Chinese have done here couldn't be done on a donor motor.

Anyone who's ever dived into one of these Honda motors knows how simple they are and tying an electric motor on the side of one was simply the easiest way to "electrify" it. Having a full gearbox is kind of a novel idea with an electric motor and I can't say I've ever seen it done prior to this. Anyone else ever seen this done?

Not seen it done, but I have a "donor", and an appropriate motor...

and enough projects on the go at the moment; don't need another one!
