40 Ah at what voltage?
swaan
2Kwh, with a 500W AC charger.

I love the simplicity and pragmatism in this design. I see also a potential for trike version. 3 wheels could give extra grip and stability .. and 1 more kW;)

What voltage for the 40 Ah? Telling us the Ah only is 100% completely and utterly useless. Either tell us the amount of energy (kWh or Joules) or tell us both Ah AND voltage.

I really like this design, having a farming background and being an EV geek - perfect match. In fact it seems a shame that lots of farming ICE vehicles have not been supplanted by EVs. The 2 main drains on road-going EVs' battery packs are completely removed - i.e. high speed (and consequently high drag) and long range.
The only addition/option I'd make is a 200W inverter for mains power tools...
Best of luck, Ubco! MW

Hoping for a reasonable purchase price here in the states! This would be ideal for travel to ice climbs when the access roads are closed/impassable. The weight makes it possible to transport on a bike trailer or heavy duty hitch-mount bike rack.

Sorry to disagree with the other, I really dislike the design. Could be simple and beautifoul. The seat looks like my father motorcycle from the '60s.
Except that, it's awasome.

I just want exactly this but with solar panels on the sides. So if you lay it on it's side for a week, you can go another 90 miles.

Really nice, looks solid, reminds me of the minibike I had as a kid. As someone commute with an electric bike daily I can see this as a fun and practical vehicle. I like that their not pretending that its a bicycle nor a motorcycle but rather a niche vehicle that neatly falls in between. Want!

the voltage is almost certainly 48 volts, failing that it's 36.
these look like standard very inexpensive chinese built hub motors for low power ebicycle applications. these are not electric motorcycle hubs, or hotrod hubs for ebikes.
28mph is the standard for ebikes. also, due to the small diameter of these motors, they look like GEARED motors, to reduce the overall weight, and unsprung wheel weight of the bike.
geared motors for an offroad application aren't terrible but A) they aren't silent B) they are more likely to fail for a variety of reasons.
ofroad application designs for e-moto are tempting for hub motors, but ultimately they are the wrong answer. the mid-drive bracket motor WITH CHAIN is the answer . why ? FAR LESS UNSPRUNG WEIGHT AND EASIER MAINTANANCE OF THE MOTOR CASE. AND MUCH BETTER CENTERED WEIGHT ON THE BIKE, and also more torque per pound of motor.
yes, even with a chain , chainguide and freewheel--------------it is still lighter than an equivelent hub motor, and the weight is centered under the rider.
this looks good, but given everything we know, this is basically an old juiced rider designed updated with back suspension and a back hub motor and no pedals.
the electronics and battery are NOT impressive, but they do seem minimally sufficient at anything less than 1.2kwh this is a piece of shit though. why? who wants to use their vehicle for 1 hour and then charge it for 4?
