It's a genereic Chinese controller and LCD. Unfortunately the LCD is not well known, so I can't find a manual for it. It's not from KT, so their error codes or any other LCD's error codes have no relevance. There's an example of the same controller and LCD here for sale on Ebay. You could ask...

Brake caliper rubbing on the motor is a common problem. It's easily sorted by fitting a larger disc and a caliper adapter. That gives you better braking too, which is useful considering your extra speed. 180mm disc should be big enough. Another problem that people sometimes get is the fork leg...

Pictures please.

Have you been through the manual? maybe there's a "hold" function or the meter has to be reset before it'll show the next value.

No. It's a lot bigger.

I've done about 2000 miles on my road bike, and I still haven't had to charge it yet.

It looks like they missed off the 1 from £149.99. If so, they'll most likely cancel. I hope you get it.

They were happy days. Long live the Beastamatic. I still have a Cyclamatic battery under my stairs that I did some experiments with. Was it you who sent it to me? Is it the battery you mention? It came from somebody on the forum.

It's not difficult to do. Basically, solder on 12 wires and put some heatshrink or gaffa tape around it. We can tell you which wires go where if you show us what you have. This pack might be the best solution if you like to learn new things and you take pride in doing things yourself. The photo...

Yes, really clear when he asked about ignoring the sense wires!

Cadence sensor all the way. Personally, I wouldn't have a torque sensor even without health problems. They just don't make sense to me on a bike for riding on the road. Cadence sensors are much more versatile. 10 years ago, cadence sensor systems were fairly crappy. They often had long delays...

The problem with the 52v ones is that even the good battery assemblers have to bodge the cells in because the case isn't designed to fit in 70 of them. The only way to get them in is to skip some of the normal safety measures. Any case that's designed for 70 cells or more shouldn't be a problem.

This is a duplicate thread. Please, nobody reply to this one otherwise it's going to get very confusing. Post in this one: https://www.pedelecs.co.uk/forum/threads/tranzx-bl03-rebuild.39162/#post-580224

You'll have to desolder the sense wires and BMS from the old pack and resolder them to the new one. It doesn't have solder tags, neither does it have ring insulators on the positive ends of the cells, so you will have to be very careful when you solder the wires. Aim for the position on the...

This very interesting article was linkesd on Endless-Sphere. Basically. The Hailong case was only designed for 48v (65 cells). To get 70 vells in for 52v, the assemblers throw away the cell holding/spacing arrangement and bodge the cells in, which brings safety and reliability issues. If you...

Can you show a picture of the drop-outs and the "adjusters" arrangement? Maybe it's not like I suggested.

I thought you'd like one of those. It looks really nice. I love the colour. I'm starting to feel a bit jealous. I just noticed that it has the big LCD, which is the version that can be derestricted and fitted with a throttle.

They used to have really good staff. I visited them several times since I became friends with Andrew, the first owner, 10 years ago. Unfortunately John Camm (RIP), the previous owner, died very recently from a brain tumour. He had already sold the business and stepped back from operations...

If it's easy to do, try it out and let us know how it works out - on private land of course!
