I made the Rambla for that and the problem was Mid drives appeal more to those who like demanding rides, the Rambla is unsuited for trail riding.The frame flexes a little and that worried me. I will be replacing the rear hub motor on the Gran Camino with the Ananda mid motor as soon as the...

I am looking for a new frame.

The monoshock fork adds about half a kg of weight. I agree that it doesn't add much as you sit up, there is little weight placed on the front tyre.

All Rambletta have suspension seat post.

I am sorry, I don't explain well. If you want to buy a battery on its own from us, say for your TSDZ8. We'll ask for details of your kit and whether you have already a charger from us. If it's for a kit that was purchased from us, then the normal guarantee applies. If it's for a kit bought...

there are exclusions when you use the battery with your own charger. Even then, there is an implied guarantee of merchatability and fitness for purpose that we automatically recognise. For example: damage in transit, missing fuse, wrong screws etc. I am thankful for all suggestions of better...

everything we sell is covered by limited warranty covering normal use for at least one year. On top of that, we honour your statutory rights to have any manufacturing defects rectified at no cost for up to 6 years.

it could be that the OP's motor is much older, before the age of motor coil winding machine.

agreed, but it may not have left the factory like that though. It looks like someone has tried to repair it and didn't do a very good soldering job so he could have cut the sleevings, strings and pulled/creased the wires. He should at least clean the burn marks.

You said it's marked as 'S' then it is. It's also the white wire. I circled it for you.

The Woosh Rambletta is not good for your weight, the frame will flex too muchbecause it's a step through frame and can be dangerous if it breaks. I would suggest converting a sturdy, good quality folding bike like the Dahon HIT with a crank drive kit like Bafang BBS01B or Tongsheng TSDZ8. The...

A b c d gnd and 5v are in your post #30. The speed sensor is S1 in #30. Google honeywell hall sensor in SOT-89 and read the technical specs if you want to know how the circuitry works. To test S1, move the magnet over it slowly. The voltage at point D will change when the magnet is in range.

We already know that c2 is just a smoothing capacitor, between pin ground and 5V. You can verify that with your multimeter. The chip it is connected to is the speedometer hall sensor, not much connected to your problem. As I said before, it could have a short and burnt. No need to replace it...

there is. a 20AH battery gives better range and better performance. Think first how far you want to go, then budget for it. If your commute is 20 miles a day, you'll need a minimum of 250WH. For a 48V system, that is 5AH. Anything bigger than 5AH will work. However, you'll should buy at least...

yes, without a doubt. You should consider to pay for top brand, A-batch cells. You also need a supplier with adequate product liability insurance in case the battery catches fire. When you buy a battery from abroad, you are the importer. In law, you are responsible for product liability and that...

Even if C2 was shorted and vaporised, that does not require immediate attention. Proceed as follows: 1. Test for short circuits. Make sure that a,b,c (Hall signals), and d (speedometer) are not shorted to either ground or 5V. 2. Connect the motor cable but leave the motor case open so you can...

it may be inconscious finger trouble but what did I do?

I like it. Simple, lightweight, understated. The only downside is the relatively expensive replacement battery and motor outside warranty (if you still can find them. The motor and battery are not common).

I plead not guilty.

I will fix it tomorrow. Thank you.
