Looking to build a Morgan Three Wheeler replica

[dandeangeli]

Greetings Endless Sphereists

I have recently build a Cyclekart, powered by a 5 hp gas motor, shown below

I wish to build a similar vehicle, though probably with three wheels, tadpole set up and take the old morgan 3 wheeler as my inspiration. I am looking for a motor that can haul about 500 lbs, (vehicle, driver, some baggage) I want to build all electric this time, rear wheel, possibly hub driven, similar to the second image.

Please direct my attention to vendors of motors for electric motorcycle related parts,

thanks Dan in Boston

Nice idea. How fast do you want to go? And does it need to be able to climb hills? QS motors has a great line up of mid drive and hub motors: QSMOTOR,0.5-12kW Electric Hub Motor & Mid Drive Motor Manufacture China

A swing arm from a moped/scooter/motorcycle with a hub motor would be a good solution. Are there any cheap second hand electric mopeds in your area? That would make a great donor bike for this project.

Under what riding conditions? At what speed? terrain? wind? etc?

I recommend you take all those to the motor simulator over at ebikes.ca so you can see how much power it will take to do the job you need it to do. While you're doing it you can also get a guesstimate of wh/mile which will help you determine minimum battery size for the range you need.


FWIW, I use a pair of old Ultramotors from A2B Metros (relaced into my own wheels) on the back of SB Cruiser to haul more than 500lbs at up to 20mph (legal limit here), on mostly flat ground with slight slopes, with some wind. It slows down in the 30mph+ headwinds we sometimes get.

The UMs are driven by Phaserunners from grin (one v6, one v1 or 2, don't know which), both from the same very old EIG 14s2p 52v 40Ah battery pack (which could stand replacing but still works well enough for my purposes, just isn't anywhere near 40Ah anymore)).

I've also used the much heavier and theoretically more powerful MXUS 450x (one 3, one 4) "3K" motors laced into the rear wheels, before the UMs. The UMs are better motors, though smaller and probably handle lower continuous power...but they don't overheat in my application.

I've also used one MXUS 450x and the GMAC; the GMAC is great, but noisy in a 20" wheel at 20mph, and I prefer total silence.

Other motors ahve also been used, including the Crystalyte HSR3548 and X5304 and an old 9C.

The X5304 was actually used by itself as the original motor for SBC,


I've used some of those motors by themselves or in tandem on the older CrazyBike2 to do the same kind of work, under the same conditions.


For details on any of them you can look thru my threads on those builds.

thanks Slo Mo I was thinking of that approach, i.e. repurposing an existing system.

thanks for your inpiut Amberwolf...what are UMs?

The word that's an abbreviation for Is in the same post, a couple of lines up.
