Re: Bafang i thin I hate you... ( HALP ME!)

I've read too many Bafang Middrive horror stories and issues to imagine that there is any comparison to the robustness of a simple hub motor system. Why do people bother?

Re: Four wheeled bikes

Usually too wide to fit on a bike path as well. The posts on bike paths to slow bikes down at road crossings seem to be set about 40 inches I think - that works well with my trike which is 32 inches wide, but I have to pay attention at speed, which is what the posts are for. That gives me about 4 in...

Re: KMX Trike with TDCM IGH & Phaserunner

Not sure if it helps as each trike is a bit different, but on my Performer etrike - a very similar build to yours, with batteries under the seat, and rear direct drive hub motor, I find that 1/16" toe-in is just right. Either side of that even a 1/16th affects the handling. You got it right with you...

Re: New em3ev batterý pack

The BMS app works nicely on his phone via Bluetooth, albeit a wee bit primitive. Getting insight into the exact millivoltage of each of the 14 cell groups ...

Re: The tipping point is just a few years out

Sounds like a good time to make a long term investment in airlines, as fossils plummet, leading to cheaper fuel supply. The price of fuel will drop very fast as EV disruption occurs as the daily balance between consumption and production will create an endless overhang of stranded oil biz assets, an...

Re: spiralling environmental cost, lithium batteries

I understand that village scale sodium based flow batteries are only a matter of a few years away based on the recent discovery at MIT with metallic matrices. They are aready at 150kwatthours/kg. with really long life span. Lithium isn't the only horse in the race.

Re: Requesting Tadpole Trike Front Hub Motor Advice

At the risk of betraying my bias on this one, based on personal experience with my recumbent trike, I am convinced you can't beat the simplicity and functionality of a simple powerful hub motor in the rear wheel. Elegance is the reason. I don't like putting power through the drive train for good rea...

Re: Full suspension semi recumbent for long range

I haven't had any regrets with the aluminum frame. The only issue I had is the slighter softness of the rear dropouts, so I used 2 opposed torque arms, on each side, to really immobilize the hub motor axle from turning in either direction. It hasn't budged so far over the 19000 miles. The mesh seat ...
