Re: Sur-Ron - New Mid drive Bike from China

If you get on the bike and peg it at 40mph you are not going to be able to get that much range. I would estimate that you can get about 20 miles in the city (under 30 mph) and 13 miles of range on the highway at 40mph, maybe less. With a 1920Wh pack this bike has about 1/2 the capacity of the Zero ...

Re: Cyclone, Brushless, 7500w motor

omeone spoke of the extra weight vs the 3000 kit (9kg vs 4 kg). I understand that reasoning, but I can tell you it doesn't matter. This thing can wheelie.
i don't like 5kg extra , put 5 litres of milk in your back pack and tell me you like it :)

Re: Cyclone motor problems

so if the price is half a new motor 40 usd to rewind people may go for it vs just getting a new motor instead. Also bad idea to remove the temp switch as that protects the motor. can you put it somewhere else on the windings ? Yeah i agree with others would pay up to 40 USD to rewind an old motor b...

Re: new cyclone 3000 w mid-drive kit?

Having tried the three designs, I'm building my next ultimate trail bike with another Cyclone 3000, and I'm placing it in the triangle for maximum ground clearance (my BBSHD was constantly catching on roots, logs, and rocks). I chose a square-tapered bottom bracket this time so that I can use the P...

Re: Quick drive by with my Nukeproof Tangent

Nice vids, awesome setup its a shame about the noise as it would be the ideal setup, how come you chose this over the the quieter cyclone3000w-6kw kits as they seem to be more popular now for the same power but quiet ? or is noise not an issue in your offroad trails ?

I have had customers come to me after having burned one of these little Cyclones up running at 2000w. They run hot, make a lot of noise, and are worth just about the $100 that Cyclone c...
