    New e bikes with small ah batteries

    My two old Oxygen Emate city bikes of 2011 vintage cannot have no assistance chosen. Once turned on you have a choice of low, medium or high, but not "no assistance". They both have unrestricted throttles that I find very useful in all sorts of ways. Probably most modern ebikes do have a no...

    Now that you have your soldering iron, you need to be careful not to head down the road of too many accessories............

    Haibike sDuro HardSeven SL 2015 Yamaha (7 Month 1600 Miles)

    That 745Wh battery looks tempting, but at a price! I have the range to do the rides I do. Only if I wanted to do a much longer ride would I not have the range. That battery dongle looks good too, and would allow me to re cell when they become available. I did a 16 mile mostly off road cross...

    Brief review of the Tern Vektron P7i .. warts and all.

    Maybe should be considering this as well. https://www.e-bikeshop.co.uk/products/electric-bike-gocycle-g4-folding-ebike?variant=42456757174510

    Haibike sDuro HardSeven SL 2015 Yamaha (7 Month 1600 Miles)

    I think I have used my battery in a slightly kinder way than you, however all lithium batteries decline slowly as they age.I have been really impressed with this one so far. I will just keep using it until it cannot give me a worth while range, and then consider my options.

    Haibike sDuro HardSeven SL 2015 Yamaha (7 Month 1600 Miles)

    Going round in circles..... On Friday the 13th of May,I rode a 26 mile mostly off road circular route on tracks I know well. When I got home I had 48% of my 400Wh battery left, equating to a 33 and a half mile total range if I had carried on riding and also consuming my battery at the same...

    Professional E bike conversions

    Although I have never used them, this company was recommended by other pedelec members and seems a professional outfit. https://www.brightonebikes.co.uk/ https://www.brightonebikes.co.uk/gallery.html

    Fine Steed

    Saw this splendid self build parked at my local Sainsbury's. I thought it might put the thread "Parallel batteries", into perspective. There would appear to be two direct drive motors, one in each wheel, and numerous batteries. I lost count.

    Can anyone compare these two bikes.

    Its not only that you can use your gears on a crank drive bike to better optimise the efficiency of the motor when climbing that makes crank drive bikes superior off road it is their weight distribution with the motor low and in the centre of the bike. Having a heavy weight in the rear wheel off...

    This is the hub that the guy who built my rear wheel used. I specified that I wanted it as strong as possible!https://www.colyfordcycles.uk/components/brakes/rr-hub-dt-540-36h-bk-135mm-6bt-black-36-hole-135-mm-qr__18438

    Can anyone compare these two bikes.

    Modern motorcycle chains are almost all o ring style with lubrication built in and well maintained last a long time. However you probably could not use the o ring technology on a bike chain as o ring chains probably cannot be made small enough. Yes I know about ebike specific chains. I was...

    Can anyone compare these two bikes.

    I am not sure that having a chain drive is a design flaw, after all lots of motorcycles have chain drives. What surprises me is why no one has offered up a properly designed stronger chain drive transmission. A thicker stronger chain, coupled to a cassette and chain ring similarly beefed up...

    Drunk e-scooter rider on Cheltenham hen do banned from driving after weaving in and out of traffic

    flecc will probably know definitively, but I have always thought that being drunk on a bicycle did not effect your driving licence. Would that be different on a legal ebike? This popped up on google, so may not be accurate...

    Can anyone compare these two bikes.

    I knew very little about integrated crank drive bikes when I bought my Haibike Yamaha. I was gently pressurized to buy the hard tail Bosch powered bike. The two things that made me stick to my guns and buy the Yamaha were firstly that the Bosch was £500 more expensive, and secondly that I had...

    Can anyone compare these two bikes.

    I have both types of motor and like them both. A 2015 Haibike Yamaha crank drive. Two circa 2011 Oxygen simple cadence sensor bikes. I would tend to agree with matthewslack general observations, with the proviso that my rear hub bikes are 4 years older in design terms than my Haibike. Even...

    Mid-drive chain and drive train wear measurements

    One thing I forgot to add to this thread. I have had generally good success changing my chain at the wear limit to put a new one on and extend the life of the cassette, but..... On some occasions when I have changed a chain inside the wear limit I have found the new chain has sometimes skipped...

    Mid-drive chain and drive train wear measurements

    I haven't tried it myself, but a roadie work colleague who kept his bikes fastidiously clean and rode very high mileages told me that the best way he had found to make his chain last was to completely de-grease a new one and then put it in a wax bath. He said that all the road dirt could not...

    Haibike sDuro HardSeven SL 2015 Yamaha (7 Month 1600 Miles)

    At my age a lot of what I do is probably not a good idea. Nealh, I am usually quite good at falling, or used to be, but there was little time or options to choose on this one. I know a dropper post would be a good idea but my rack attaches via a seat post carrier clamp. I've only started...

    Always a good idea to inspect cables...

    I cannot see any bare wires in your picture. If everything is working as it should wrapping the effected area in good quality electrical tape and trying to re house the wire where it will not rub might be enough at this point. I did the same when I found a similar thing on my old Oxygen a...
