    eMTB purchase

    You might get some responses by posting in the which bike shall I buy section rather than in here which is for reviews. If you do, include more info such as proposed use.

    Building a e-roadbike

    And you will need to take it to the moon to use it legally. I'm not trying to be prissy, but riding an illegal bike regularly in a densely populated area such as London is a bit too obvious, even if you aren't bothered about breaking the law. Other posters have pointed you in the direction of...

    Air compressor

    I use a basic diy compressor for blowing water out of the pipes on my static caravan prior to winter. Similar spec to the one in the link. It will do what you ask of it, but don't expect lots and lots of pressure, or to be able to run air tools. They are also designed for lightish...

    Service

    I doubt it needs a dongle.

    Service

    Most cyclists fettle their bikes as they go along, so there's no annual service as such. Some prep the bike for winter with different tyres or put on mudguards. Full sus mountain bikes have bearings and bushes which need replacing periodically to keep them operating sweetly. Not my area, but...

    Wireless Gear Shift and Brakes on eBikes?

    Too much chance of official displeasure, even if the contraption can be legally classed as a tandem. You would have a hard job convincing a magistrate that something which looks like a motor scooter isn't one. Particularly when that magistrate is being told by a known and trusted traffic cop...

    Gearing and motor

    Reminds me of the Emperor's New Clothes. The Bafang Max Drive performs just the same as a Bosch Classic, and even looks like one - a bit clunky. Nothing wrong with that, but it's no advance, merely a copy of European technology of which there's a long history in the Far East. It's also a...

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

    The first two posts tell us the OP got through a cassette in 1,600 miles. Very low mileage, but the use is relatively harsh. Biscitt has the same problem after 700 miles of nothing harsher than cycle path use. That simply should not happen. Telling him the answer is to use eco is equivalent...

    New Yamaha powered e-bikes at £1399

    I'm sure you've thought that through nicely. There's a bike for every ride, as they say, but you now have a few more bases covered. Nothing to stop you slapping Big Bens on the Giant come the better weather if you find you much prefer it to riding the Saracen.

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

    I've ridden a Yamaha bike and reckon it has similar grunt to my Bosch bikes. The claims by the makers support this view. The combined power of a not particularly fit rider and the power of the motor is what the rear sprocket is being asked to handle. That combined power is no more than that...

    Hi - decision time

    Worth having a look at the Wisper 806. A bit more quality than a standard 'no name' Chinese folder, but still relatively cheap at just over £1k for the smaller battery version. Leaving aside brand, 20" wheels - with balloon tyres - is as small as I would go unless you only ever want to do a...

    Gearing and motor

    Good stuff. Pilot error probably had a lot to do with it, but there might have been a software glitch which was sorted by turning the system off and on a couple of times. One thing to be aware of is Bosch bikes don't like pedal pressure when the pedals can't turn. That can happen if you are...

    Bosch battery re-celling

    No worries, interest already from another forum member so one way or another I won't be stuck with the battery. Bosch batteries seem to last well - better than many others - but some of the early ones must be getting a bit tired by now.

    Bosch battery re-celling

    The meeting point is negotiable, but the price is not. I've no wish to be awkward, but however you cut it I will be bringing the battery best part of 300 miles and there will be some extra faff for me to achieve the hand over. One of my Bosch bikes will almost certainly be for sale in the New...

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

    There seems to be general problem with top gear slipping on Yamaha powered Haibikes. I wonder if it's caused by the chain line. Not much you can do about that, as it's governed by the frame and the relative - and fixed - position of the front and rear rings. Trying to get away with a using...

    Gearing and motor

    Ah, that takes me back. Some of the early Bosch bikes acquired that popping noise, which went away of its own accord on some. The factory fix is to remove the cover and redistribute the white grease inside - there's not a lot of it, so it isn't packing job. A home fix, which doesn't always...

    Gearing and motor

    Thousands of trouble free miles on my two Bosch bikes. I like the ride of the system, so would certainly buy another. It would be the safe, and in some respects, boring, choice. But safe and boring has its advantages when buying such an expensive consumer goodie. The latest Yamaha would be...

    Bosch battery re-celling

    Got to be worth a punt for you at £100, plus a ludicrously over-priced cup of coffee at Thurrock services.

    Bosch battery re-celling

    It's a 2012. Little, but regular, use, always left part charged. Last time I gave it a run out - couple of weeks ago - it had the same range it always had. I'm in the North East which gives us a problem. I have a small matter to attend to in Kent, probably early January, which would see me...

    Gearing and motor

    I agree about the vid - to a point. A parts tray may have hampered the camera/spectator view, so that could be the reason for plonking the stuff on the ground. Interesting comment about the Bosch battery getting hot when climbing. I've not noticed that, although the couple of times I've...
