    Bike or kit? I have confused myself!

    If you have £2100 to spend on a new e-cross KTM, spending £600 converting the Aspect leaves you with £1,500 in your pocket. You can then spend it on a very nice weekend push bike! plus the converted electric commuting bike will attract less attention from thieves too. just a little tease, of...

    faster alien

    you can derestrict the bike by going into the LCD settings, usually by holding the + and - buttons down simultaneously for 5 seconds. Press on/off button to select next item, select the maximum speed and increase it. hold down on/off button to exit. However, there is not much scope for...

    European regulations, one more time

    even if the vehicle passes inspection and approved as pedelec, it is still not EN15194 certified, so you still can't ride it in other EU countries.

    is it only expensive bikes that have throttle mode no need to peddle?

    Most German bikes do not have throttle. Some German bikes (Kalkhoff) have startup throttle to help you at traffic lights or changing gears on hills, they can get up to about 12 mph - plenty to get you going. Almost all Chinese bikes have throttle. The ones with LED display can go up to 12mph on...

    European regulations, one more time

    xipi builds off-road bikes, clearly outside EN15194. In Alien case, if the kit is the same electronics as in one of their certificated imported bikes, they may be able in principle to issue individual COCs. Somehow, I don't think this was the case, not for the Golden motor kits anyway.

    European regulations, one more time

    A, B, D are correct. C. I don't know of any example that fits your criteria. I can speak of my own bike, the BBS01 is certified, my bike is EC certified (but not EN15194 because it's not electric). I don't have an EN15194 test certificate and I don't have an EN15194 label affixed to the bike...

    European regulations, one more time

    the cost of certification is not much - typically, a Chinese factory will pay for the certificates (usually SGS) for bikes that they reckon will sell for more than 2,000 pieces in their first year. That works out $1.5 per bike in the worst case scenario. Small modifications of this bike (eg...

    Getting the wheel apart

    this case will remind self builders to go easy on the Amps. Those nylon teeth will bend and heat up - it's cheaper on the long run to buy a 350W motor where a 250W would do. Also, think of the crank drives, they have helical steel gear mesh, a lot stronger than the straight cut on many geared...

    European regulations, one more time

    You can buy a motor with EN15194 test certificate (most 250W Chinese motors do have) but it's just covering the motor, not the bike. The bike has to pass EM test, configured with the motor. That will require obtaining a test certificate - costing $7000 for one or 2 bikes in Shanghai or £10,000+...

    Out of the top 10: # 2 Momentum: Price:£1,095 Rating: 5/5 Verdict: “Cheaper, faster, better” Cheaper but not faster nor better Chinese bikes. #9 Wisper: Price: From £1495 Rating: 3/5 Verdict: “Sexy black, macho, top-end Chinese bikes” - where are the kudos bikes? My guess the top 10 brands...

    8Fun BBS-01 kits

    I'd like to see more kits as the way of giving us the perfect e-bike at lowest possible cost and we all owe you a big thank for the help and support you give to self builders on this forum over the years. I think that the role of the dealers is to bring in the kits, provide initial support and...

    8Fun BBS-01 kits

    it just goes to show how difficult it is to sell and support kits. I am a fan of crank drive kits, still think the BBS01 is the easiest to fit and best at preserving the feel of the donnor bike. Broken LCDs and throttles are not 8-Fun's own faults, the problem with the motor unit in Belgium is a...

    help with recommendation

    You'll need excellent credentials before they answer the phone! Bosch only sell to the top 100 European bike manufacturers, not exported to China and not available as kits. It's difficult to define better. Chinese products are cheap and rough. German products are well designed and expensive. It...
