Although I have no personal knowledge or experience with that particular bike, it appears to be one, as several have already said, to avoid like the plague (or should one say COVID-19 nowadays?) It is sadly not alone on the e-bike market! Do not get caught out! Furthermore, may I recommend that...

Bad luck. Andy

Dumb Question, is the battery fully charged as far as you can tell? The pictures I find on the web show it as being a rear hub bike, with small (20"?) wheels. So basically, whatever is wrong should be fixable by a reasonably competent DIYer, IMHO. Do you own/use a multi meter? If yes, can you...

Further (good) reasons to completely avoid this make of bike...... Many thanks. Andy

You need access to and how to use a reasonably accurate voltmeter, to discover what has gone wrong. Till then, it will be difficult to offer any useful help. Sorry. Andy

Are you going to document this repair, with photos and put them on Pedelec? Andy

If what you say is true, then the new charger will not operate correctly. I looked at the picture magnified, and I believe its a barrel connector, similar to what my bike, and the previous one as well, used. A query to the seller, noting the name of the bike, and that it has a 4 pin connector...

Did you actually look at the picture of the replacement charger, and identify the DC charging cable and connector? It appears to be only two wires. There is nothing on the other two wires from that replacement, except possibly a short or a diode.... As, if I understood it fully, the original...

Have you read my update above to my original post you answered, that will verify exactly what is there and what is not! Simples! "Elementary my dear Watson":):):) Andy

Sounds great, thanks for the update. Andy

The very first consideration that you should make is what type of road are you going to be riding on. If its a main road, with the usual morning and afternoon traffic, you should seriously consider the dangers or idiotic car drivers, who do not like being slowed down by any bikers. If there is a...

Looking at the picture of that replacement charger you kindly posted, it appears that the only connectpr between this charger and all the various connectors, is ONLY 2 POLE!! Check the picture out carefully! Therefore, it is apparently totally misleading to assume that because there are 3 or 4...

Thats a far better price! Andy

I am really interested in how you get on. I am sure that I am not alone. Best of luck Andy

Possibly the controller has been programmed for too high a current, you need to get that reduced, but do check the MOSFET again. You have a brushed motor, one of the fields may be shorted, guessing only. I do not know my way around brushed motors for e-bikes at all, maybe someone else can give...

Will you buy one? They are around 10 UK pounds from a UK based Supplier on ebay if I remember correctly, just look on there. There are basically two versions, one with a round display for the motor signals, and one where the same LEDs are in a line. I am told that the one with the circle is...

Possible. Is there not a bike shop person or owner here who could explain why 4 pins? Guessing, possibly a temperature sensor? That alone is an important point for when buying a bike, a standard two pin charger can be bought all over, just get the right connector, observe polarity and you are up...

Very true. Expecting a chain, with maybe a powerful motor, and good leg muscles, to last much more than 1,000KMs, in hilly country where I live, is asking for trouble, plus the cassette is often worn quite quickly as well....On my first e-bike, I changed the cassette after about 5 years of very...

WOW, really expensive..... Thanks. Andy

I agree that range is important and is affected by type of motor (hub or mid), gearing, weight of bike, weight of rider, wind resistance of the package, style of riding and and and.... So that should all be taken into account when discussing range, its simple physics!! In general, good hub bikes...
