The access problem is easy to solve. Put folding pedals on it and lever screws on the stem clamp so that you can quick release the clamp and turn the bars in line with the frame with the wheel still pointing forwards. That makes the bike completely flat. Anybody that has to bring their bike into...

Whether it's covered by warranty depends on what's wrong with it. Say you dropped the battery and damaged the bit where the charger goes. That wouldn't be covered. On the other hand, if a connector had worn out or a component in the charger blew, that would be covered. I can't think of any...

The 80/20 rule is for single lithium cells, not ebike batteries. The cells have a max voltage of 4.2v and minimum 3.1V. That's a 1.1v range. The 80/20 rule applies to that range, so 80% = 3.98v and 20% =3.32v. You cannot use that range for an ebike battery because balancing happens above...

Most ebike batteries use top balancing, which is basically an overflow system. By charging right up, the high cells overflow, which lets the low ones catch up. you have to understand the difference between looking after the cells and looking after the battery. The 20/80 rule gives you maximum...

I think these guys have enough experience to make valid comments. Cannondale “We take rider safety seriously at Cannondale and support the use of disc brakes precisely because, by offering superior control and modulation, they make for better and safer riding overall. Lalonde continues...

The problem is the speed of the motor. At legal speeds, there is insufficient back emf, so the controller will allow maximum current all the time. If it's a KT controller set to current control (torque simulation), it'll be OK as long as you don't leave it on level 5. If it's any other type of...

The BBS** motors seem to have different settings from each supplier, and some of them are appalling. I recommend that you install and try your motor. If it's OK, leave it as it is. If you're not happy, get the cable and adjust it.

None of that will do anything to lengthen the life of the battery. If you do need to do it, it can only be to calibrate the estimation of range if you have an LCD that predicts range. The ideal range of use for lithium batteries is between 20% and 80%, but most ebike batteries only balance when...

How are you going to change the gearing with belt drive and Nuvinci gears?

Three possibilities i can think of:- 1. They're nuts. 2. They haven't tried them. 3. They don't have disc fixing points on their bikes and they're jealous.

The flashing red light shows error codes. Flashing evenly is no error code, then any uneven sequence denotes an error, like three flashes and a short pause is error code 3. One of these can be useful for testing output from the controller. It also tests the hall sensors and motor phases for...

I have hydraulic disc brakes on my main road bike. They're infinitely better than the high-end rim brakes that I have on my other one. The modulation is better so you can put the tyres right on the edge of slipping for maximum safe braking, while as the rim brakes are less consistent and can...

This is the modern left wing. Everything they do is right. Therefore when somebody does or thinks something different, they're wrong and against you, which makes them a fascist so you must hate them. You will see them holding a placard saying "no hate" while they hurl every hateful abuse and...

You need a 12 FET controller for 48v. Bear in mind the battery's maximum current. You need about 5 amps of headroom to avoid cut-outs.

Generally, you don't need torque arms on steel forks for a motor like that, though I'd fit one on the brake side for added safety. In the photo, it looks like your drop-outs are 5mm steel plate. Have a look at them to see if they look strong enough. It also looks like you have a 10mm bolt-on...

Here's the manual for your LCD. https://gocarlite.com/wp-content/uploads/2018/10/C600E-USB-V7.0A-instructions2.pdf Hall sensor error means:- 1. Motor connector not fully in. 2. Motor cable nicked, especially where it comes out of the axle. can be if you pulled a zip-tie too tight. 3. Water in...

The 15 amp controller will overheat because its only rated for 7 amps. 15 amps is the max it will give, which would normally only happens occasionally, but with only 15 amps, the motor most likely won't be able to get up to its efficient speed, so it will be drawing the maximum current all the...

Are you sure the forks are aluminium? The ones in the photo look like steel. Test them with a magnet if you're not sure. Those kits work, but they're pretty awful compared with alternatives that don't cost much more. The main problem is that you only get one power level with the pedal sensor...

The three motor phase wires and the white block with the motor hall sensor wires are easy, then you have yellow and black for the brakes. The rest is unconventional and similar to one I'm working on right now. Mine doesn't have quite so many connectors and it was really tricky to work out...

In case you missed it, here it is. Get plenty of popcorn and beer in before you sit down in a comfy chair to read it. Don't forget to do the quiz, and if you get all the answers right, you'll need to take additional health insurance. https://www.pedelecs.co.uk/forum/threads/sqeaking-brakes.35405/
