i thought it looked great - especially the ergonomics, it's quite narrow and seem to have a good riding position - then I notice what looks like an ungeared/direct front hub drive, which, on a 250kg plus cargo trike would be a fatal flaw.
My thought too. Their text on control of torque suggests they are probably using very high currents at times of high low-revs demand to try to deal with that problem, akin to the Lynch motor method, but of course that will greatly depress range.i thought it looked great - especially the ergonomics, it's quite narrow and seem to have a good riding position - then I notice what looks like an ungeared/direct front hub drive, which, on a 250kg plus cargo trike would be a fatal flaw.
yes cant imagine any geared motor's plastic gears surviving, or i guess the chain or IHG on a crank motored version in hilly terrain, though the electric pedal taxis in oxford street must have found a solution?My thought too.

But I think these heavy load transport trikes are really only suited to quite flat areas, regardless of 250 watt rated motor type.

but that's 4800 euro for a base model...:^(If was in the market for a cargo trike the award winning versatile eZee powered Radkutsche Musketier would be my choice https://www.flickr.com/photos/99101558@N06/
The one referred to by the OP has a direct drive motor, no gears in the motor.yes cant imagine any geared motor's plastic gears surviving, or i guess the chain or IHG on a crank motored version in hilly terrain, though the electric pedal taxis in oxford street must have found a solution?

The Lynch motor is specifically designed for this sort of job and was used by Cycles Maximus in their trike taxi/van, so they may be using that. It's not a hub motor, it drives the rear axle. Although rated at 250watts, at near stall point it can exceed 4kW, so will climb anything, just slowly.yes cant imagine any geared motor's plastic gears surviving, or i guess the chain or IHG on a crank motored version in hilly terrain, though the electric pedal taxis in oxford street must have found a solution?
