    How far do you want to go?

    Speaking of which, what happened to the forum ride in County Durham?

    ebike battery explodes

    Could be. There are stories locally of the Germans flying over the cathedral, probably on their way to/from Sunderland, which was a target because of the shipyards. Another story, which may or may not be true, is when a few bombs were dropped near Durham the cathedral was shrouded in mist...

    ebike battery explodes

    Someone was bound to mention the war in this thread. Not that I'm any better. I saw a party of German tourists taking photos of Durham Cathedral the other day. I was tempted to observe the only reason the building is still there for them to admire is the inability of their bomb aimers to hit it.

    Maximising battery range

    I have tried it, several times, on tour setting. Seems to me the battery meter is one of the better-engineered features of the bike. The traffic light meter on my Brompton Nano behaves as you describe. One light out and the battery is about 70 per cent used. When the second light goes out...

    Maximising battery range

    As I posted, the Bosch battery's meter does go down fairly uniformly, certainly the first four bars, so multiplying, less a little bit, is a reasonable methodology. Seventeen x 5 = 85, which is why I said '70 or 80' miles would be possible.

    Maximising battery range

    I wouldn't describe my eco test as 'fun'. As things stand, the only way to have a long ride with carefree use of the assistance is to carry a spare battery. The Bosch battery is fairly compact and a spare would sit nicely on the carrier. What wouldn't sit nicely with me is the cost of buying...

    Maximising battery range

    I wondered the same myself, but having ridden 40+ miles on eco, the assistance does do a fair bit more than make up for the weight. There was a burst of quite strong assistance on one hill when, I think, I got the cadence up a bit.

    Maximising battery range

    Not eating the batter would do more for your range.

    Maximising battery range

    I wondered how many miles I could wring out of the 11ah battery on my Rose/Bosch bike. To this end, I set off on my Whitley Bay circuit on eco setting - assistance level one of four. There are five bars on the battery meter and each lasts for more or less the same distance. On eco, I got just...

    Electric or motor technie geek advice?

    The sensor looked OK, and there is a fair bit of tolerance for the gap. Have you checked the spade terminals in the battery holder? I think someone on here had one of them bend, and because they are in an upward pointing cup the area can collect dirt.

    What's the best car battery?

    Good batteries, Bosch. (I hope)

    Endeavour BS10 400Wh

    Mmm, another thread from a new member about the Endeavour BS10. I hope it's kosher.

    Puncture Proof Inner tubes

    Some retailers quote the weight of the tube. In the absence of 'puncture proof' ones, common sense suggests a heavier tube will be more durable.

    Puncture Resistant Tyres

    As has been said, Marathon Plus for puncture resistance. You shouldn't need special tubes, but as you are taking the original tyres off, worth putting on new tubes if only to get rid of those stupid Woods/Dunlop valves which come as original equipment. Schrader is the best valve to go for, the...

    Nice. First impressions are important, so it looks like you are well set.

    New from Woosh, mileage predictor

    Works nicely for me on Macbook/Firefox. I agree with Hattie about the name, as soon as I saw 'predictor' in the thread title I thought of pregnancy testing kits. The obvious alternative word is 'calculator', although it has too many syllables to be snappy. Nothing better springs immediately...

    Ebco ucr60

    Suspension seatposts, particularly cheaper ones, are a bit of a dead loss. Although for most ebikers saddle height is not so critical because they are not trying to wring the last bit of power from the human side of the propulsion equation. But that still doesn't cure the irritating pogo stick...

    NuVinci CVT (Automatic Gears) Hub

    The 'Alfine' is supposedly a better-engineered hub than the 'Nexus', irrespective of gear numbers. But I think I'm right in saying the latest Nexus 8s have Alfine guts, so the two hubs are equal in that respect. As Artstu says, the main benefit of the Alfine 11 is higher top gears, which you...

    Looks like Continental say between about 50 and 70psi, which is what I would expect: Continental Cycle Tyres UK Edit: Good advice from Martin (above) about the fork.
