I agree with you here. A conductor with a high temperature rated insulation can run hotter and will be capable of shedding more heat as this ability is proportional to the difference between the conductor/wire temperature and the ambient temperature. PS Sometimes cables/conductors are made...

Does adding weight really slow down a bike that much or is it that the bike feels slower? In theory, for example, it would appear that if say a 85KG rider with a 15Kg bike, (total 100KG) adds say a freewheeling geared motor and battery (5kg) to their bike, then the most speed they should loose...

I have a number of older/high miles bikes with cheap chrome steel sprung forks with some rust . Other than a bit of sloppiness (bushing wear) and one fork seizing , they seem to ride on the road ok. There is no rust on the bottom near the dropouts which can be an issue with the flattened tube...

Just checked, my LCD5 has L settings. To check mine, I scrolled through the P and C settings as normal. After C14 flashes, hit center button quick once and C14 stopped flashing. Then press the up and down button together for about 10 seconds in my case and this brought me into L1. This also...

There are 'L' settings on some KT LCD's and controllers which allow you to force the controller's LVC to say 30 volts which is an option but has its drawbacks. I have never actually tried it but the settings are on my LCD's

What's the question?

All my bikes have throttles as well as pedal assist but I generally pedal with pedal assist and use the throttle only as required when pulling away from stops, extra boost on hills, and when dogs chase me down the road. I suppose I might consider myself as a moderate user of the throttle...

Front hub motors have a little bit of an advantage here in that they dont appear to have that problem and can be a good choice. Of course, the non motor ordinary rear wheel can break spokes but its generally easier to deal with this and other rear wheel problems / get replacement/ local bike...

With bad knees, I would keep away from torque sensors. I think a throttle would be ideal. The bike below is designed for up to 25 stone weigh and I think would be ideal. Best of luck and ignore the negative comments. https://wooshbikes.co.uk/?bigbearplus

In a normal ebike setup there are a number of overcurrent protections that I can think of.. The battery BMS FETs should trip a little over the batteries nominal max current rating. The battery normally has a back up fuse of higher rating over that again. The controller normally has a shunt...

What you need is a good pannier rack. I have just come back from a hilly ride this morning. (76 Km). I was carrying a total of 32 Ah at 36V volt battery paralleled and weighing nearly 8 kilo. No problem with a good touring rack and keep the weight low. Also plenty of room for snacks, rain...

Sometimes you can keep a wheel going by a quick replacement of the broken spokes only. I have often got a pliers and bent 13g spokes into a tight circle to get around the disk. On my bike, the 32T freewheel cog was smaller than the motor hub. All my spoke breakages were at the j bend. To replace...

Both the older and newer versions of the instruction manuals (attached below) state "If the battery is not used for 24 hours or longer, it will automatically go into sleep mode. Press the power button on the battery for three seconds" This might explain although I have never seen it happen with...
