Motoring law? Cycling laws regarding ebikes just seems to be almost anything goes. Still amazes me that Bosch can get away with motors peaking close to 800W with a so called 250W rating. I'm sure it would take only minutes for a electrical engineer to show such ebikes aren't legal and should...

If only the cargo part has the motor why install the controller and battery on the bike itself. I would of thought you would want to keep all the main ebike components on the trailer and just run a control panel on the bike. I notice the bike itself is a flying pigeon mountain bike. You don't...

I've just charged two of my 48V batteries and made the point of putting my hand on the two identical chargers at the mid point of charging both charging exactly the same model of battery and both chargers weren't even warm to be honest, I could barely feel any heat at all. Both batteries have I...

If you want the maximum hill climbing assistance then be aware some of the lighter road and hybrid bikes with mid-drive have lower torque motors that are in the same ballpark as hub motors in performance plus you have all the disadvantages of a complicated motor, massively increased drivetrain...

The way I'd buy a secondhand ebike is factor in the battery is toast and needs replacement even if it doesn't. Is it still worth buying if the battery fails in a couple of weeks because its end of life? An ebike is not like a normal bike the battery is a huge part of the value of a ebike and can...

I've not heard of changing voltage for mid-drive motors before but then that is probably because most have a controlled eco-system of parts. Bafang may be different but typically mid-drive has the controller board built in so you can't upgrade the controller so unless it was dual voltage...

If I had a folding bike to take into shops I'd probably take a folding bike bag and put it in that. I'd get the largest trolley and just take it around like that so the folding bike is always with me especially if it was a high value bike like a Brompton or ebike. I can't see them complaining if...

So the typical cheap power supply's supplied with cheaper ebikes which tend to be quite light presumably switch mode power supply's as definitely no weight for a transformer inside are these good or bad in theory (obviously practice may vary). I remember reading about someone who had an early...

I've seen some Parkside battery packs stated as 20V which I realise a lot of companies do when they are actually 18V packs but what annoyed me about them is they claimed 80Wh capacity on the pack 20Vx4Ah when clearly they were not a real capacity of 80Wh. 18Vx4Ah is 72Wh. No idea on how good the...

Yes the 25KM/h assistance speed limit is surely the priority. A throttle gives much better control of speed than a cadence sensor typically so is much safer. Maybe the UK law will be reinstated as the EU law doesn't really do anything sensible at all that we started complying with in 2016. Of...

Just to clarify you have a standard 7 speed freewheel and it screws too far onto the thread of the hub motor to the point the largest cog is touching the motor hub side plate. As you say you will need a spacer to prevent the freewheel screwing on to far. If it was a non-standard freewheel not...

I don't have any battery packs at 19.2Ah or more, 2 are 48V 13Ah (624Wh I think) and another is 48V 15ah. Fairly low end generic batteries, 2 have the Samsung 2500mAh cells, the other pack is Littokala with 21700 cells. I've just realised stupidly that I may only touch the charger at the end of...

Is this just an issue with higher current chargers as I have 4x 2A chargers, 3 x48V (2 the same model) and one 36V and they seem to only get luke warm or maybe its related to the size of the battery or how much current the BMS allows. I think I saw a warning previously that if you carry your...

Legal hub motors won't match the hill climbing ability of the most powerful mid-drive motors but its really about how much hill climbing ability you need. I think the average human produces a consistent amount of torque between 20-50Nm with older less fit riders closer to the 20Nm figure and...

I've never seen bearings in that state before, they are impressively corroded to the point where they have lost their smooth state. I'm still loving the fact a bike of such age and condition will get resurrected. I do think you will need to inspect everything thoroughly though for safety sake...

The discharge rate will depend on the controller you buy and how you set it up if it has a LCD display to go with it or perhaps the default values if it doesn't. Hub motors just work with what they are given by the controller. Despite the 250W rule controller output varies enormously. Some...

What does the Speed Signal connector do? I've got a controller to use with my Bafang motor that has just arrived. The one connector I don't understand is the Speed Signal connector which I first thought maybe a throttle connection as it looks the same but the 3 cables are red, white and black...

If its something like a voilamart kit and looking at your first image I can see the direct drive motor hub in the background that looks like it could be or something very similar they work best with the throttle controller and may not have a connection for a LCD display/LED bubble button display...

It turned up today, all seems fine, the charger turned up a couple of days ago so will need to fit the connectors. Above I wrote XT60 but its actually a XT30 connector it has and that is actually what I have already, I bought a multipack of them male and female from aliexpress sometime ago. One...

I've no suggestions to make on the build but hope you keep the thread up to date with progress and a few pictures. I've thought about making a shopping ebike out of a old post office pashley bike the type refurbished as Elephant bikes. So if one of them comes my way fairly cheap I will...
