I think the demand for your products will be principally from the corporate, people who want to run bike hires. There is no need to worry about the split between the two.

whenever I asked a manufacturer for charger in their docking stations, they stop talking to me and yet, you can't have a public shared e-bike without charging and docking stations. I must add that there are a couple of French systems for that.

I am not sure you can find a controller that runs with the Suntour kit which has its own integrated torque and pedal sensor. Then you will also need to buy a new LCD.

Inunell, do you intend to integrate your charger into docking stations?

No can do.

inunell is the boss.

Col d'Aspin Altitude : 1489 m Length : 10.80 km (6 miles) elevation : 785 m % average : 7.27% % Maximal : 10.0% To climb 800m = 15AH battery Thank you Rupert1 for the feedback.

don't buy a fat bike for conversion! Most fat bike conversion kits on ebay use direct drive motors, they are totally wrong for use on fat bikes where you need a lot more torque than that type of motors can deliver. For fat bikes, you should only consider either crank drives or rear geared hub...

removing cladding is the wrong tactic. There are so many 'chimneys' in any building where flames and smoke can funnel, what are we going to do? add fire barriers to all the risers? The right tactic is to install sprinklers.

The information about range is pretty useless as you have found out. If asked, I usually look at the shape of my customers before replying. If the person looks like 12st or under, that will be 8WH per mile, then add 1WH per mile for each additional stone. 14st = 10WH, 16st = 12WH. After...

This Rixen Kaul front basket will fit nicely to the Big Bear LS. I use one to take stuff to the post office every day. http://www.chainreactioncycles.com/rixen-kaul-shopper-folding-bag/rp-prod47418

the Grenfell tower was intrinsically safe when it was built. Later, the addition of plastic double glazing windows, PIR insulation and pretty rain cladding that added an external chimney to it has made it unsafe. It's strange that nobody mentions the professionals who supervised these...

I can agree with you on that. The Big Bear has no load speed at 20mph, it is optimized to pull heavy load at 17mph, so can't match a CD bike with the same output. However, I did hook the GSM CD motor to the bmsbattery kit, I reckon it would match the CX and more.

the Big Bear I am selling has a 20A controller, it has about the same output as the CX.

that's where we differ. I have to compare motors on the same test rig, you don't.

the Bosch CX does not have a throttle - can you figure out how to test? If I hook up the bmsbattery kit to the BPM and the same guy pedaling as hard on both bikes, the BPM would win.

I did hook up a BPM to that kit. Same bike, same controller, same battery. The tests use throttle only to get to 800W ASAP. The only difference is the motor wheel. Did you use the same bike, controller and battery in your tests?

I use the bmsbattery kit Q128H, 48V 20A controller. The KT LCD that comes with the kit displays also in Watts. I hooked it up to a variety of motor wheels and also the GSM crank drive. The kit pumps into the motors exactly 800W in all cases. My result is different, the Q128H is good but the...

I gave my reasoning and supported it with evidence by others. Unlike you, I don't think that suppliers are blindly led by the factories that they buy from. Their choice of Bafang SWX02, 7 and 8, all 140mm motors are probably founded by the same reasons that led me to select the SWX02, after...

I like the idea. You get plenty of time to take the bike out for a proper test without being pressurized by anyone.
