    Viking MT Tobin controller problem

    OK, it should work then. The only problem is that the LED control panel doesn't give access to all the settings you need. You might have the wrong PAS signal pattern selected or it could be switched off altogether. There's no way of knowing without the LCD.

    Updated fast-folding ebike gets a cleaner look, sheds some weight

    The folding mechanism isn't new. The GX folding Gocycle has been around for 18 months without any reported problems.

    Updated fast-folding ebike gets a cleaner look, sheds some weight

    Voltage has nothing to do with it's power. It's not full of Chinese components. It was designed from the ground up by British engineers (ex McClaren) in London. Every single component is bespoke, except maybe the brake levers and pedals. You don't need to worry about repairs because they're...

    Viking MT Tobin controller problem

    The throttles always work independently from the pedal sensor, and are optional. Try pedalling backwards to see if that works. It's possible that you've bought the wrong control panel. Which one did you have before? Which controller did you buy?

    Cyclotricity, help fault finding

    The 9th wire (white) is for a speed sensor. You don't need a speed sensor with a direct drive motor like yours because the controller can use the hall sensor signals to calculate the speed. You can buy motor cables from Ebay...

    Just fitted a TSDZ2 on my cargo bike, now gearing is wrong

    That doesn't make sense. Did you say it the wrong way round. Your chainwheel is bigger than before, so will raise the gearing, not lower it.

    Commuting Bike

    I only mentioned it because we get an awful lot of people come on here and say something like, "I've just bought X bike. I love it, but I find the 15mph limit too low. How can I change it?". In nearly all cases, they've bought the bikes that are the most difficult or expensive to adjust. It's...

    Resistors on voilamart front wheel hub

    You can use any type. It's only the value that counts. When the halls go, it's possible that the mosfets in the controller would blow as a consequence if someone tried to give full power afterwards. You should check the resistance between the battery negative and each of the three motor phase...

    Updated fast-folding ebike gets a cleaner look, sheds some weight

    The Gocycle is a fantastic bike. They're very powerful, light, fast and full of technology. They're a bit of an anomaly when it comes to hub-motor vs crank motor comparisons because they do everything so well (except off-road riding, obviously).

    If you get 5v between the red and black wires, there is something wrong with your battery or its connections. Those two wires are connected directly to the battery wires that come into the controller from the battery. Check the voltage on the main battery connectors that connect the battery to...

    Commuting Bike

    Yup, twist and go. The law changed in 2016 to disallow the fitting of full-range throttles on new bikes. People will argue that it's not illegal to fit one after you buy the bike, though that's never been tested in law because nobody has ever been prosecuted for having one. Some new bikes 4mph...

    Flit 16

    The motor has very little to do with how much power you get. The power is decided by how much current the controller gives it and the battery voltage. In simple terms, power = volts x amps. The motor is only a transducer. It converts that electrical power into motive power and waste some as...

    Resistors on voilamart front wheel hub

    It's common to have pull-up or pull-down resistors on the hall sensors. Their value would be around 10K. the exact value isn't important. Anything between 5k and 100k would probably work. Now we come to the tricky bit. Yours appears to have two in series, which doesn't make sense as there is no...

    Brexit, for once some facts.

    You never will, but you can look back at the last 20 years or so to see what it means not to have it.

    Ebike charging using Street EV chargers for electric cars

    I used it for a camping trip of about 50 miles each way. We stopped for about 40 minutes each way to give the 20Ah battery a boost. Luckily the campsite was deserted, so it was no problem to do a full charge there. The enclose and exhaust extension quietened it right down, so I don't think...

    Battery charging, how often

    Ideal Ideal is to store it about half-full in a cool place or somewhere where it doesn't get warm, but I never bother. It's all theoretical. maybe you can extend your battery life by 20% if you do everything right, but for most people, that'll be the difference between 4 years and 5 years, but...

    Cyclotricity, help fault finding

    5.0v and 0v! It's late, Neal. It can also do that when you have a faulty mosfet in the controller, but most likely one of the motor connections or the motor cable damaged.

    Ebike charging using Street EV chargers for electric cars

    That Kipor generator weighs 10kg. I now have the one suggested above that weighs 9kg. I bought a child trailer for £40 and knocked up this one out of 3mm plywood. It tows really well, though the bike I towed it with had a Bafang BPM motor running at 30 amps. Both have been shelved and are...

    Battery charging, how often

    The advice above is good, though nothing to panic about. Do what's most convenient for you. Just never leave your battery empty for any prolonged period, like several days or more. Another guideline is that you should aim to charge to full, but again it's nothing to panic about. If you haven't...
