Very possible to run without one, but the system must be properly designed for it.

I made a water cooled one ...not the prettiest but it passed a 8 psi leakdown test. Now that I made one I know my next attempt will be betterhttps://uploads.tapatalk-cdn.com/201...8dc4595503.jpg

" I am not quite sure what to make of this. An electric-powered sidecar rig patterned after the WWII German Army BMW R71? Does it come with a machine gun in the side-hack too? However the lack of any pictures of the ReVolt and that disclaimer at the end of the article has me scratching my head. Is this someone's fantasy and they are trolling for dollars? http://blog.motorcycle.com/2018/04/1...torcycle-game/ "

THAT's what I like to hear! LOL

Whenever I showed the bikes, people were always assuming I was all about the green. What got me started had nothing to do with green technology. I started imagining what a big-ass electric motor would feel like in a bike.

When I had the R5 fitted with lipo cells and an ultralight pack, it was the first time I scared the crap outta myself on a motorcycle, since riding my bored, ported, pipey as all hell RD350 in the '80s. It was like hitting the power band, but all the time.

Rock on! Hope you have as much fun as I did! "

Honestly, im a speed freak. I would love to get up to something like 200hp. Realistically though, if i can cruise at 70ish mph, have a range of 100-150 miles im happy.
I can keep the speed riding for my turbo gsxr.
I dont know how to post pics here. I can show you where im at. "

" It looks like the whole powertrain/frame of an Alta with a vintage fork and a rear tube frame grafted on. Clever and well executed. "

" Looking through the slide show and thought, wow, they really cleared up space in the rear triangle area - I wonder how they accomplished that. Then I noticed the pack peeking out of the fairing in the second pic.

Warren replied to the thread More electric scooters.
" Any of this stuff put out at auto shows, by car companies, is greenwashing. They now that none of their customers will ever actually buy these, and if they were foolish enough to pay a premium for a bike or scooter with their car's logo, it would sit in the garage gathering dust, next to the 1980's Nordictrack.
