Raht Racer pedal assist trike

[intakexhaust]

I've become intrigued with the advancement of pedal assist bikes but then came across this on youtube. This is on a whole different level -pretty cool yet doubt its efficient for any distance. The electricity draw has got to be significant vs. regenerative + pedaling.

Interesting the builder received a govt. grant. ----???

I really like the shape, the design, and the thought behind it. I like how they used motorcycle components rather than spindly bicycle parts.

For a slow speed commute, I think it might do fairly well, but you would be sucking other car's exhaust, and not be able to see very well, and sweat like a pig if it were warm outside.

This is very cool. Makes me want to quit my day job and invent things.

Flashback to 1996 - - Remember the Sparrow?


Electric tech is rapidly advancing in bikes.

Got an electric bike 4 years ago= FUN!
goes 20 miles -without pedaling- @ full speed (20mph).
many more miles range when I 'assist' by pedaling.

Still have to put up with sneering road bike douches who
call out while I pass them up hills, "you're cheating" (all the time)
Hopefully that attitude will evolve in a few years.

Great commuter, hot days are a joy, instead of sweatfest.

Yep, we're already paying for it.

I don't recall seeing anything in the Constitution that would authorize such payments ..............

Indeed I recall the Corbin. A business just adjacent to my bro's shop had one collecting dust and buried in a corner. Eventually was sold for pittance, recall it was $300. Under the dust, it was clean and complete machine.

Anyways, back to e-bikes / velo machines-
The vid of your full size folding e-bike seems most practical.

I recently picked up an older but never used recumbent two-wheeler for my wife. Pedal powered only, it currently has a Sachs 3 speed internal geared hub with 7 speed rear derailleur. On its maiden voyage, rode it approx. 12 miles in dirt path, gravel travel to hilly asphalt. Its not speedy but capable and surprisingly comfortable.

Plans are to add a minimalistic front hub motor kit 350 watt / LCD dash / trigger throttle, 36 volt li-on batt.'s. Nothing fancy, no-regenerative. The kit I'm considering will drive exclusive but more suited as pedal assist. I also want to keep the total weight at or under 35 lbs.. This is my first experience with e-bikes / pedal assist.

I had a thread a while ago on electric kits for bikes (typically hub motors).

Anyone tried anything lately?
