    8fun conversion of new Carrera Subway Hybrid bike

    8fun conversion of new Carrera Subway Hybrid bike

    Good glad your happy with it so far and its not caused you any real problems. Should be a solid build. Have you got any close up pictures of the bottle battery and its fitment? As Flecc always pointed out that sometimes the weight of the bottle battery vs what the holes are designed for can...

    Giant Lafree Twist Dilemma

    If you can spare £200 I'm sure one of the other retailers on the forum can help you out with a new battery. Will require some tinkering and wiring to get it sorted.

    Lights (again, sorry)

    Thanks who ever recommended the Cree 502b ultrafire torch. Good spread on the light and for £21 for 1000 lumen torch light it's good. Much better than my old one that was stolen. I've attached some pictures for reference. I got mine from a uk supplier. But if you wait a bit you can buy it...

    8fun conversion of new Carrera Subway Hybrid bike

    I still pedal alot. Well all the time as I still like the exercise. But I probably should run a torque arm as a just incase safety. The rear drop out on the bike is large though. Much more than the front as give said. Maybe I should speak to a friend about cutting me some for a couple of...

    8fun conversion of new Carrera Subway Hybrid bike

    On my rear bpm build I'm not running torque arms. Only the anti rotation torque washers. The axel was a tight fit but didn't need filing. FrOnt wheel 250 should be fine without. As long as you have the washers.

    Picaxe Query

    I like that description D8veh. Its interesting how minds develop and interests from a young age. I played alot with Meccano and Lego and spent alot of time taking things apart rather than playing with them. I think I found it more interesting in finding out how it worked, rather than it...

    BMSBattery Controller Amps

    Main wires like phase are usually bullets. The res the connectors are quite univeral but you may as well change them for what you want. There's no garantee that they will be perfect anyway. As with most stuff out of China. Sometimes they have got the actual wires the wrong way round on some...

    BMSBattery Controller Amps

    Another reason why Electronics are far more interesting to play around with. Tuning a car takes considerable about of precision and engineering. Monkeying about with an Ebike takes very small effort to get it setup up to how you want it to perform. Electronics are also alot cleaner than...

    How many ebikes are replacing cars?

    E-scooter or motorbike would work well. Its just a bigger platform than a bike. I've toyed with the idea of making one but keep thinknig the simplicity of a bicycle is about as easy as it gets. The things would be so relaible as well providing you have enough battery power. You could even...

    How many ebikes are replacing cars?

    It's replaced my car. But I still have it. Just not used it's since feb. Seriously don't need it. We have two cars and if I want to drive I use my partners 107 that gets 60mpg. An I hardly ever use it. She needs a car to commute daily from Birmingham to Coventry. We live in the city and my...

    DIY crank drive ideas please

    I love the idea of a hub driving through gears. As hubs are generally very quiet. Unlike friction drives or Rc motors with super high rpm's. However I don't think they really look that stealthy and there never really appears to fit in with the look of a bike. However you would get the best...
