Will the slimmer inner tube still remain centred on the wheel especially going over pothole or rough ground?

Are 20x4.0" inner tubes OK for 20x4.25" tyres? I need to replace the rear inner tube on my bike which has Innova 5189–10 tyres.

Fab. Thanks.

As the post title says. I last charged the Samsung 36V 21Ah battery for my ebike back in March 2022 but due to illness haven't been able to ride and it totally slipped my mind. Then today reading about increasing incidents of fires caused by dendrite build up EV car batteries I suddenly...

Saw this fun divertimento and thought of the Li vs Pb-H2SO4 battery thread...

Don't apologise :) Yes it's rear hub motor.

:cool:

I asked if it could be changed, not made faster. Some people have dodgy knees you know. :)

The walk assist speed of my Bafang C961 display is set at 6 km/h. The advanced settings in the display allow for the overall max speed limit to be set, but obviously I don't want to change this. Is there a way however to change the walk assist speed to something other than 6 km/h?

At the very risk of your uncompromising disdain and acid-tongued vitriol, I've never come across the phenomenon of contact burning – I'm just a lay person, not an engineer. What is this in the context of using and charging ebike batteries. Thanks.

How do you mean?

Yes, I've read a little and seen microscopy videos about dendrites and the nasty after-effects, i.e. explosive fires. Since I have no option but to charge indoors this is one reason I'm a little nervous about ensuring I'm not doing anything to unnecessarily put my family in danger.

I have checked and you are all quite correct. I now have absolutely no idea whatsoever where I got the figure of 17 °C from (possibly something to do with work), but I would have sworn that's what I read! It does in fact say not to charge below 4 °C (40 °F).

With the cooler and wetter weather approaching, I (a newbie to ebikes) was looking for some help and advice on best practice for caring for batteries. I have a bike with a Samsung Lithium-Ion 21Ah 36V 756Wh battery. The bike's user manual only says not to charge the battery below 17 °C [edit]...

Not an ebike battery fire, but an example, I guess, of charging a battery for too long. Terrifying moment hoverboard EXPLODES
