what happens if your feet slip off the pedals at speed with a bafang bbs mid drive motor? I get winded just at the thought of all that high speed pedaling even if only nominal input is required.. Since my bike is no lightweight and neither am I on the flat the added mass of motor and battery...

Nothing to do with e-bikes, sorry.. so if mods decide to wipe this- cest la vie.. Im stuck replacing the hinges in some upvc windows that no longer open/close easily. The new hinges on the 1st window attacked need fixing in new screw holes right next to the current holes - so close that if...

Perhaps dont give up? I can get you started on determining the 5v and ground connections in the plugs.. you just need a multimeter (£10 ebay/amazon) and some short lengths of thin stiff wire to probe the female socket pole holes.. for test wires i found the snipped legs of electrical...

What if anything have you configured in the controller settings for your motor, Out of the box some expected features may not be enabled until set.. iirc my kt controller was not pas enabled out of the box for example.. and iirc parameter C2 needed attention too.. and when it came to the...

if considering solar who is good to talk to/buy from? Ive had a few cold calls on the landline that did not inspire much confidence and dont know anyone local who has taken the plunge, except for the one unfriendly neighbor.. (took a parcel misdeleverd to me round b4 christmas and got shouted...

Not built an emp but did go to skool ;) If such a device were feasible, simply using the same tech/materials employed to direct/target said pulses is all thats needed to shield against it.. a system to kill scooters with all of them Bt 4+ enabled already exists even if still vapor see dutch...

Dont even bother with the trailer as fixing the hitch will probably not be a viable option.. But do take a heavy rucksack as its all about the ability to move a mass, so just increase your mass ;) if the bike can carry you and a heavy rucksack of a similar mass to the loaded trailer, what...

Woosh bikes and whisper bikes, both contribute in here and will probably welcome a sales call inquiring about their bikes.. and going by their input in here both could easily supply your needs.. an ebike system has 3 main elements the battery which needs to be able to output sufficient power...

What is the gradient and length of the climb on this hill? and what mass do you want to carry on the bike. Do you want motor only hill climbing? or are you happy to contribute to the climb yourself? most ebikes climb hills ok, mine needs a lil input from me but i remain sat in the saddle comfy...

Watts = Volts X Amps. superficially 'on paper' , yes its more complex but.... Most ebike kits come supplied with a 15a (peak power) controller a 36v battery fully charged carries 42v of potential. so a 15a controller supplied with a 42v battery can provide 630w which is significantly more...

Dont be misled by motor wattage ratings, a motor with 350w stamped/etched on it is illegal to use on the rd and could be way less powerful than systems with motors rated at only 200 or 250w.. Front wheel hub motors are more prone to wheel spins and loosing traction than rear hub motors as...

What does the 3rd wire connect to within the old cradle? a few pics would be useful..

Many of the 'high end brand' mid motors have 'dongles' available at stupid expensive prices i think 'MSO' (maximum speed off) is a good keyword for google etc..

The battery connection points are its 'terminals' one labeled Positive (+) the other Negative(-) a wire or metal tool or any other conductor of electricity touching both terminals simultaneously would 'short out' the battery, this could be very bad. I am not suggesting you would do this...

Check your motors controller limit iirc its 18a, so a 30a battery should have ample head and shoulder room. Quite the build? we like project pics in here.. what sort of range are you aiming for? whats the bike gonna be like to ride when out of juice???

We all had to pick up a meter for the first time.. :) Check out you tube for ebike battery voltage testing too That meter will be fine for dc voltage testing, Not much to it, select DC Voltage (V=) on the meter dial, use the red probe to probe the positive battery terminal and the black...

Looking forward to good news..

Hi Welcome, How important is derestricting? can you return the bike still? I dont know your bike but generally a 'built in' bike is significantly harder and more expensive to modify than a 'bolt on' bike !! And depending on manufacturer sometimes impossible to mod.. If its simply a ' I...

Everyone in the know seems quite impressed with your '250w' motors specifications(aka 750w elswhere). But if you are intending a motor swap I would be happy to help you out and buy the old junk motor for 15 euros + pnp to save you all the bother... ;) Simply over-volting your current hub...

Cheers, while i have no need or current want, its certainly nice to know for if/when a need arises ;) If 'the only shop in town' i might have been tempted by the motor alone but not the kits on offer no no no.. I only included the links to qualify the claims made for the '200w' motor..
