To test throttle find the connector and poke your Black probe in to rear of the Black a Red Probe in to rear of Red you will see 5v with the battery on. Next place the Red probe in to the back of the signal which is Blue or Orange /one is signal and one is lock. You should see 1v with the signal...

I just went to the payment and it came up Free shipping so not bad £147, buyers might need to budget another 25 - 30 for duty as it is couriered by DHL/FedE/UPS. D2D is 6/7days. 42nm max is quoted but see they also mention it can give 50nm isn't too shabby for a hub and 11.1 gear ratio, 25a is...

Yes those are the bearings then simply buy replacements that have the same part number, type in in ebay and many sellers will show up. 6001rs I know is the cover plate bearing and 6902rs is a freewheel or cassette bearing. My cassette had two (stacked with a shim in between so make sure you...

I can faintly hear a noise but it doesn't impede the motor turning by the looks of it. If a bearing is at faulty you should be able to feel it if you have your hand on the axle and rotate the wheel by hand. Show us a pic of the inside of the removed cover plate . Also check the freewheel gear...

GBK do the small gbk100 series of silver hubs, look identical to Q100/AKM. Also available is Bafang SWXH.

The Gocycle GX is nearly 18kg.

Did the chain slip off the front chain ring on the inside ?

Although unfashionable a bike cape for riding or a bike cover for when it rains and left locked outside.

Problem down to spokes breaking is down to badly built wheel (incorrect spoke tensioning) also the 12 & 13g spokes used although thicker do not have the elasticity of 2mm 14g spokes, which most if us use successfully on hub wheel builds with out issues. When I got my Oxydrive kit a few years ago...

Is the sensor orientated the correct way and is the gap between disc and sensor about 1 or 2mm.

The one you like the most, that said Oxygen have a very good rep for CS.

You will need to continuity check the throttle wiring for an intermittent break in it with a multimeter that has a beep function. One of the wires will probably be giving an intermittent contact causing the bike to take off or simply replace the throttle with a new one. Sometimes you can run...

Nothing is totally sealed with external batteries, as K has said they are ok for riding in the rain. Issues appear when left in standing rain for hours on end or the user decides to use a hose pipe or pressure washer. If bothered you can add a small dob of grease to the contacts. For the...

Show a link to the kit you bought. 17mph may be it's ultimate speed not due to the RPM winding but the controller programming.

Why would I waste my money on something I don't need. It takes a few minutes to open a battery and then some simple measurements to usually find any issue, I prefer to know what is at fault with a battery to recognise a issue when it crops up. By delving in to batteries and repairing them or...

If you open the throttle whilst at it continuity check the three wires to see if a fault is in one wire esp the signal. I once had a rearing bike do to a throttle issue and it was the signal wire which had a break in it and occasionally caused intermittent contact.

The fact it took 10 charges as you said to achieve full capacity shows that the so called 0v charger isn't anything special, all it is doing is raising the low cell voltage a little but can't balance fully. In most cases of low cell voltage opening the battery and charging via the BMS sense...

Double check the bullets connections at the motor end, as they may cause an issue. Think about soldering direct or solder in a julet 9 pin connector. When testing phase expect to see about 9 ohm to 15 ohm or so, all three should be the same, do the same for phase to V+. You may see the same or...

I couldn't here anything on the video's and the hub rotated quite well. The end plate bearing if rough you will be able to feel it and here it as you rotate the axle slowly, other wise the planet gearing is lacking grease. Clean it up and regrease with a non petroleum grease and don't spare the...
