36v offers 50%, more power /range & speed over 24v, the voltage makes no difference to bike size. Ideal World now and then have offers on their folding ebike when there is a T.V offer on, so another possibility at the lower end of your budget. The Pendleton is a good shout but if you lack the...

Generally can't disagree with what you have said at all. Though I do have a 7s charger which will not allow any charging what so ever if over 39 v, I can only assume it sees a near full battery. Once the battery has been discharged a little more it switches on and allows charging .

Don't connect it up, you will cause damage to the battery or controller by means of shorting. The batteries polarity needs to be correct.

I think for aesthetics with the name Wasp , colour scheme would ideal need to be similar. Like early Fords only available in Black and in this case with yellow decals. The play on words suggestion is a good name ' Wisper IT ' or ' Moth' sounds good. Paint finish can be personal for me gloss...

Not trying to be pedantic. In terms of legality it is still not legal, no matter what is done to the kit, a 500w hub is rated 500w no matter how much or which way you try to spin the theory.

You silly boy !!!

You may do, theoretically a 36v battery will increase the hub speed and torque by up to 50% if the controller or system isn't speed limited. Though there is a risk the higher voltage may smoke the controller, in which case you would need to get a new one. You can check the capacitors in the...

You will probably need to get an ext cable version and don't forget the correct diameter for your seat tube. Chain reaction ,PlanetX or any other online or store supplier.

You can wire in a 12v supply it has to be in series with 24v battery and not parallel. You can use any 36v controller but will need a compatible lcd and probably another PAS sensor if you sensor is for a torque BB. Or simply just by a kit from this seller for a bit more speed, just select the...

A higher voltage like that can prevent the bms switching. You need to manually discharge the high string with a drain source and monitor it down to near the others, wire up some car headlamp bulbs in parallel.

36v is 42v when fully charged, 36v is it's nominal charge rating. The sensor is a PAS or torque sensor the red led pulsing just indicates it is working. If you currently have 24v battery pointless fitting any 36v kit as it will run even slower.

Assuming you have wired up a bms, double check all cell string voltages. At 35v it should charge if they are all fairly equal.

Using a Schrader adapter with presta's eliminates any damage concerns when fitting or removing pump connection.

14mph average speed for the 28 mile trip is good going, though fitness improvement will eventually knock time off as well up to a point. Terrain conditions will vary so times will change and as Gubbins has mentioned you will learn to use the system more efficiently by use of gearing and modes...

With throttle you are stuck with fast and full amps which will take it's toll on the battery sooner, with 5 levels of pas you will have more control over power delivery. 1 is next to useless for my needs but if you had young kids or a wife like mine that doesn't like going fast then it is ideal...

You will have to remove the BB and get a longer one, measure the minimum axle length you need and buy the nearest length BB, or simply take in to Halfords or where ever and get a one. If it's only a couple of mm you might get away with grinding a little off the crank arm inner face :eek:.

Battery configuration is quite easy. 24v = 7 cells in series. 36v = 10 cells in series. 48v = 13 cells in series. An example 10s 4p; A cell of 2500mah = 2.5ah and is nominally 3.6v per cell, 4 cells are joined in parallel to give a battery capacity of 10000mah/10ah this = one cell...

This thread has been neglected of late. Some pics from todays ride out. New park and ride opening as you enter Westcott A25. Some nice animal wooden sculptures in Gomshall A25, all chained up to stop them escaping in to the wild. Near to home a couple of Shetties mooching about.

Ordered wrong Gaadi tube and it arrived with P valve. A bit of amalgam tape on the stem to fit Schrader size hole and use a brass adapter for my Schrader pump.

Does it happen if you leave the throttle disconnected ?
