    There are so many to choose from - help

    Crank Drive Motor Clunking Noise

    The article about the German designer is interesting and aligns with my viewpoint. The remaining article about US definitions on ebikes is irrelevant because all of these cases are have already been defined by the EU, which applies even yet to the UK The pedelec definition and derogation...

    Hi just to be arguementive the law about one motor not sure... If one construct ed an assembly of 10 black and decker electric screwdriver s around the rim and friction drives , it would generate 250 watt of mechanical power , or even 100 motors from scaletric cars. The legislation does...

    Hi as a phone to make and receive calls probably not much worse . this performance is set by the GSM consortium. As an in pocket computer gizmo it would not be at the races I assume that at 600 pounds you are talking Samsung galaxy s6 or s7. These Samsung's and their competitors typically...

    Um 44 Ebike battery propriatory?

    Hi I have had another model of ebike from this same manufacturer . 1. Are you sure that this is actually a Li ion battery and not the earlier MeH type? There was a transition between the two types in 2007\8 . When this occurred they changed the footprint for the connectors. Not that it...

    Brexit, for once some facts.

    Fellow posters please get a grip. Personal abuse is neither funny or helpful in any debate. The first posting on this by flecc, nearly 8000 posts ago identified the purpose of this thread.. a debate about the advantages or otherwise of the brexit controversy. Name-calling is no substitute for...

    Crank Drive Motor Clunking Noise

    That video proves nothing of any value. A bigger powered motor goes faster than a smaller powered motor ... surprise!! From the limited view of that crank motor it looks like a kludge. It looks to be driving the crank via an auxiliary chain. There are therefore two chains in use. Since the...

    Hi - decision time

    Hi My limited experience is that unless you have pressing reasons to get a folder that an ordinary model is better. My first ebike is \was a folder and in all the years I have had it it has been folded I think ona maximum of 4 occasions over some 8 years. I thought that having the...

    Batteries too expensive!!

    Hi IR, I am puzzled by your use of the disagree icon, since you cannot know whether my alleged competence is factual or false, you have no basis on which to disagree. On the other hand were you to use a dislike icon, that would be fair game. To recap and put things in perspective. The O P...

    Batteries too expensive!!

    Hi my comments must be restricted to the current pattern "Bosch active " which has a three pin oval connection. I note that your model is rectangular and has more connection.

    Batteries too expensive!!

    Hi , there is no voltage present on the output pins of the Bosch battery when it is removed from the bike or the charger. A safety measure. There is a third pin and I assume that that is used to initiate power when plugged into the charger or bike. While it would be possible to require a...

    Batteries too expensive!!

    Hi Somewhere I picked up info that it was derived from the electric power steering gear on Audi . Presumably they modified the windings for 36v operation. Again why would that not also have been derived from other motors used for other functions

    Batteries too expensive!!

    But ebikes are currently available from about 500 £ in supermarkets, a wide range of reasonable ones at 1000, excellent durable ones from 1500 and varying degrees of luxury from 2k upwards. ... The future has arrived. As against cycling not being mainstream, look at major cities in Asia...

    Batteries too expensive!!

    It is almost a certainty that Bosch are using Panasonic or Samsung product. But are they buying them at the same price and or spec as either the retail cells or the remaindered product available from some of the no name brands. I would assume that battery cells pass through a mass production...
