Help! My next project

[Benjahmin]

I forgot the brake switch. I used a hydraulic switch and used an old cycle computer magnet cable tied to the brake pipe. Switch is held on with doulbe sided tape, may need glue.

Motor labelled and ready to go:

The motor itself is labelled. The bike isn't - yet. I know it needs to state the speed limit and also the manufacturer, but who the hell is that? AKM (the motor), Carrera or me?

The label on the motor looks good to me. Similar to my homemade label for my Mxus motor.

As far as I'm aware a factory ebike should have a label on the frame, listing name manufacturer of bike, voltage (48v max), wattage (250 max) and max assist speed.

But with conversion kits the label with this information should be on the motor, but obviously name of manufacturer should be the motor manufacturer.

I'm a bit unsure if you need the max assist speed on the label of the motor, but it would do no harm to have it on there.

This is mine (after several attempts).

Finally got all the bits I needed and the time . So, in the spirit of 'show us the pictures or it didn't happen', here's the build.

Build went smoothly despite some brain fog:

Had to build a front wheel too with a new hub. I've really enjoyed the wheel building process, pity I waited to my seventies to learn this skill. Both wheels ready to go:

I ended up having to swap the bottom bracket for one with a longer spindle to accomodate the pas. Handlebar layout took a few goes to get everything to fit.

The bike fully loaded.

Now a couple of questions.
The reason for doing this was to end up with a fully legal bike. The motor itself is labelled. The bike isn't - yet. I know it needs to state the speed limit and also the manufacturer, but who the hell is that? AKM (the motor), Carrera or me? Does it need anything else?
Second question is a set up one. The display is programmed to give walk assist throttle until pedals are turned, then it gives full speed. Great ! Only thing is full speed throttle continues after pedal rotation ceases and only reverts to walk assist when throttle is released the operated again. As I understand it to be legal it should revert to walk assist as soon a pedals stop. Anyone know the setting, the Chinglish is doing my head in?

The law just says that the bike has to be marked with the maximum assisted speed. How you do it doesn't matter. From memory, the correct settings are P4=1 and C4=3.

You forgot to say what it's like to ride. how does it compare with that Ezee thing you had?

Haven't had chance to try it yet. All the weight is now on the rear end so not sure how it's going to feel.

It should handle wheelie good. Why didn't you want to use a downtube battery?

The rack battery has too much life left in it and I have no other use for it. Plan is to use it up then get a 48v downtube battery.
