    2017 Giant Full-e problem

    A quick look on Giant's website suggests they do for the current models so I am sure they do for your older one. Another possibility is a capacitor of some sort in there. What happens if you try to switch the bike on with no battery fitted, does the display still light up? Normal behaviour for...

    2017 Giant Full-e problem

    The standard Yamaha one has a battery, I would expect the Giant has too. I believe it was a CR2032 in the Yamaha one.

    Box for rack to carry stuff.

    Your problem with the saddle is likely because you have too much of your body weight on it. Mountain bikes are designed for your saddle to be higher than your handlebars to keep weight on the front wheel to make cornering better and keep the front down when climbing steep hills. When you have...

    Help! 'Starter button' wanted for Bafang mid-drive (and Mahle hub)

    I actually use a dropper seat post for a similar reason. Where I ride is off road in the Alps. Often I will have to stop on a steep uphill section to get past a gate etc. If I tried to start with seat at normal height even at fairly low power I would get wheel spin. With the dropper post fitted...

    Ebike robberies

    Of course there is, they are final delivery vehicles.

    Box for rack to carry stuff.

    I'm guessing but if the reach of that bike (saddle to handlebars) is correct then the saddle is far too low.

    Thought I'd treat myself to a new bike

    After surgery for a hernia earlier in the year I was feeling very uncomfortable over rough ground with my 2016 hardtail Haibike. Thought it was time for a full suspension so treated myself to a Merida E140. It's much more comfortable over the bumps, I know I could have fitted a suspension post...

    Yet more stuff in the media on battery fires and kits

    There are more than enough pictures and descriptions of legal conversions / ebikes on here that terrify me.

    Re-celled battery but no pedal assist

    Be very careful sticking things (including multimeters) across the. battery terminals when the battery isn't switched on. If you draw any current the Yamaha battery can shut down with an irreversible fault. 29.2V suggests the battery isn't switched on and is just showing a little bit of leakage.

    36V Bosch tool battery for e-bike use

    Given that part of the appeal of using something like a Bosch tool battery is the relatively small size, high current capacity (for the capacity of the pack) light weight and expected reliability why do you then want to start throwing likely substandard Chinese copy parts into the equation...

    Build spec by committee, might that include you?

    Bear in mind the all up weight for a young fit professional cyclist on a road bike is probably less than half the weight of the average ebiker on an ebike. They also aren't always going as fast as 15mph uphill. I can hold either of the ebikes I have had (one Yamaha, one Shimano) at max power...

    True a wheel. Bike shop or DIY?

    That's more likely to be a dent in the rim with rim brakes. Even if a wheel is out of true (a little) the brake caliper will just move sideways as the out of true part comes past the caliper. Disc brakes would prevent that issue in the first place. I personally wouldn't ride an Ebike with rim...

    True a wheel. Bike shop or DIY?

    Why do you guys need to true wheels so often. I ride up and down Alps mainly off road with some rocky descents, haven't needed to true a wheel for years. I don't think I have needed to true a wheel for in excess of 20 years since I bought my first actual 'good' bike.

    Ebike battery fire

    36V is the nominal voltage, fully charged is 41.5 even on a Bosch.

    Illegal ebike crackdown Coventry

    Isn't that what they said about drugs 20 or 30 years ago, look where that has got us now. Innocent people being caught in the crossfire having a Christmas drink or killed because her mother heard a noise outside and looked to see what it was. Carry on like that with vehicles and there will be...

    Rear derailleur size

    You won't need the hanger extension, just screw the 'b' screw in until the change to bottom gear is smooth. Don't mess about with extra chain links, just buy a new chain.
