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.

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

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/

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?

but that's 4800 euro for a base model...:^(

The one referred to by the OP has a direct drive motor, no gears in the motor.
The Radkutsche is not cheap but is a quality machine and popular for commercial use in Europe, it's eZee motor has hard wearing composite gears not nylon.

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.

of course, like a stoke monkey I guess

completely forgot about those.. on the plus side it looks DIYable if one can get a nice cargo trike frame..
