thumbs up for being green

VERY WELL BUILT BIKE. IS THERE SOMEWHERE I COULD SEE SOME MORE DETAILED PHOTOS OF THE BATTERY PACK SETUP AND SUCH.

Where did you get this motor.

[webboist]

Just checked the hs3540 motor out. Looks fast but it's only rated at 500watts which looks rather low to me. Compared to the other older crystalyte motors which are 2000w to 3000w watts. It also says that the hs3540 motor only goes up to 48v. Do you think that the hs3540 motor could be used up to 90v or would it burn out. If it is used with a 90v supply will the wattage go up to from 500w?

Any hub motor can take at least up to 100V no prob.. Voltage is not a problem... But the current is a real limit of hub motors. I have few 250W hub motor that i push 100V in them no prob... But i wont push 100V at 50A into them.

The Crystalyte hub motor are rated 750W.. not 2000 or 3000 like some are claiming... but Yes they can take burst of 20kW

The nine continent hub motor are rated 500W and they can take 10kW burst ( few sec during acceleration) and 1500W contionuous...

Thanks for your reply. I see if you go onto the hobbyking website they are now doing a turnigy 10 cell 5 amp lipo battery. They also have some nice external outrunner motors the turnigy ca120-70 rated at 20hp. I am new to the ebike world in your view is it better to go with the motor in the hub or a external motor? What hub motor is currently the best and most powerful is it still the 5305 called the brute 7240 or is there something better now. Your videos are great please keep up with the

The 5305 is the slowest motor of the X5300 serie ( X5 serie) but it'"S the most powerfull about torque for the same amp the controller put in the motor. The 5302 is the fastest but you need a controller that can give ALOT OF AMP to drive it in the performant range. The X5 model are 5305( slowest and most torque), 5304, 5303, and 5302( fastest and lower torque) But the production of these motor apparently stopped and they offer now the new HT amd HS serie High Torque and High Speed

Hi can you inform me what controller make and model you are using thanks

Hi

This is an infineon 50A 72V brushless controller that i modded to 100V 150A

Awesome! I am not sure what e-bicycle laws are like there in Quebec but i know the OPP would be all over me if i tried to ride that here in Ontario. I still want to do my own conversion now. 50km commute with a constant speed of 80kmh for me. Looks very do-able.

nice helmet! what is that opening at the front? sorry I'm a n00b at biking.

[Bamchucknorris]

LOTS OF TAPE!!! nice job anyway

[norbique]

Thank you for doing these tests! Your work makes me think about converting a bike myself.

[bananaphonehome]

Awesome ride. Awesome duct tape as well.

I would have cut through traffic just to blow that Harley away though...lol.(well the first once at least)

almost has me considering a hub motor for my first build now...

[cypher955]

hub motors are very quiet...I have two...a forsen hub motor bike that goes 31 mph and I have 5303 crystalyte that I haven't installed yet...my advice would be to get nimh, nicd, or lithium batteries...I have lead acid and don't have much range

[luc59457]

That place looks familiar

[karmabike1911]

good test. like the helmet :)

[ahset]

nice ride! very fast!
