Re: Sortimo electric cargo trikes

The whole "leaning trikes are a solution in search of a problem" argument is silly. Put enough aero on a two wheeler to hit 35 mph on 500 watts (on level ground) and you'll have a scary, dangerous vehicle in a gusty side wind. Put enough aero on a tadpole to hit that same 35 mph on 500 watts,and you...

Re: 1890 E-Trike patent

"Wow, they even had the sense to put the two wheels in the right place."...not only that, they'd figured out that a short wheelbase reduced the likelihood of tip over. Good thing, considering how high the center of gravity looks to be on that rig.

You would think that the solution to big vehicles in the central city would be easy...just jack the prices of car size parking places up until no one can afford them.

Re: Going AWD

That leading link springer fork is welded steel. If the axle flats fit the dropouts, those are near 1/8" thick, and you aren't running more than 350 watts, a torque arm is not necessary. Not a bad idea, mind you, but you don't need to build in the sort of strength you'd need at 4x that power.

Re: eTrike Build Log - Custom Frame / 78v Lipo / MXUS 3000w

Just an FYI... tadpole trikes are much more stable (less likely to tip over) when the center of gravity is well forward and low. I'd find a way to get the battery pack up front, below the crank.

No one has mentioned the Morgan 3 wheeler yet?!!! Three wheels, so it's a moped not a car, even with an electric motor. 20's style body, so it looks good with tall, spoke wheels, simple curvatures to the body panels, for easy home building...and it has surprisingly good aero. There was a top availab...
