This company sell bikes on Gumtree, they always have a number of bikes advertised there and their offerings not all are low value.

I usually work out tyre pressure based upon the 15 % tyre drop rule as discussed in Bicycle quarterly PDF article I downloaded some years ago attached. Taking your overall weight as 130Kg and your bike as a city bike weight distribution 35% front 65% rear. (could be worse on an e bike) The...

That looks like a fat bike mod, it seems to be more common with them but failures are reported by no means exclusively with these. Again there is a pattern the modified design just puts more stress on it. The failure seems to mostly occur at the circlip slot on the RHS as seems to be the case...

Personally I would not be worried too much by axel play unless severe. I would be worried about the axel breaking, more so that it doesnt seem to have been addressed. While most probably wont suffer from this, you always have the thought in the back of your mind, will it break in the middle of...

If you go by the number of posts on forums the TSDZ2 is the least reliable of any of the well known kits, but its also the best supported. The thing that swung it for me was that there are lots of spares more so than any other option. Thats potentially because there is a healthy market for...

A picture is worth a thousand words, this is quite a negative reply, the point is there is more to come form this source, this is what I was trying to alert others to. So what, that's his business model the clue is in the name, not really relevant though the point is this is the first good look...

Saw this new vid on youtube might be of interest, looks at DM01 and DM02. New for 2023, DIY ebike conversion motors from TOSEVEN! my first thoughts. - YouTube

Ignoring motor efficiency this would give you a peak of 720w but you would probably have to disable the street limit to get that. You would also have to input 180w yourself to get it.

You could do this but if the current is limited 12A your going to get a maximum input of 576 w anyway. I would say exceed 250w for a short period as much as you need to get you up a hill. The real constraint on how much power you use is the durability of the motor ie dont over do it and...

The legislation refers to a continuous output of 250w for a given period of time. if you exceed that time presumably the motor should fail. The 250w thus refers to the continuous rated power output, not the maximum available. The screen shot implies you are putting an absolute limit on. This...

Have you considered the blue gear, I say that because I assume the noise is from the motor. I dont see your pedals jumping are they? If the pedals are not slipping its not the main sprag clutch.

Hi, It would be helpful if you Identified what part you need a picture or a description. I looked at the bike on the net it looks like its put together with generic Chinese electrical parts. As for the other normal bike bits these should be available from bike shops or on line retailers. But...

I would not consider a rack battery although they do show one above the beneath the down tube option (the one I was referring to) I dont know a way of mounting one on a full sus bike. I had thought of the softpack option as I have used the Enerpower solution with a 48v 15ah battery, in this...

Something like this might work for you I saw this on the e bike choices site here https://www.ebikechoices.com/tongsheng-tsdz2-review/ Its a TSDZ 2 conversion but that shouldn't make too much difference. I would check your battery dimensions and clearances before committing, watch the front...

The obvious question is this still under warranty, there is obviously a fault that may be rectifiable under the original warranty ie the failure of the connection. As you've lost the keys you will need to go back to e life to see if you can get replacement keys or spare parts to repair...

Oh I'm afraid that's not what I found when I was in the market. I was looking for a 48v battery in the smallest case available. There were numerous batteries available with lower densities, larger cases and less than optimal sizes. There were few sellers, for small case batteries around 14ah...

For small frames There are a number of problems with the current offerings, the first is that most batteries on sale dont use the most energy dense cell options. Most batteries are only offered in standard cases which usually dont fit and even if you can get one to fit it runs up against the...

I was not intending intending to post. I just picked up on those beam rack suggestions, they all looked doubtful. I know with racks generally you have to be careful with clearance in small frames I always double check with stuff like that and you cant trust forums because most people dont seem...

Hi Im late to this but the rear rack solution might have an issue. The rack suggested by Woosh might not be suitable for your bike because of its frame size. Its hard to tell from a pictures for sure but it might foul the rear wheel. The basic idea is sound but topeak make a specific design to...

You fail to answer or any proof official body can indeed the fact that you resort to quoting references without any detail whatsoever would suggest that you dont. The bodies may know better but without any evidence they address this issue is unresolved. Your argument is effectively I said it...
