How is the current controlled with a hub motor and controller, so the duty cycle controls voltage by the length of the duty cycle and that is fed through capacitors to smooth it out but in a hill climbing situation where the motor is bogged down at a slow speed and using maximum power and we...

You could try a bit of copper grease on the back of the brake pads, copper grease helps prevent high frequency vibration. I use copper grease a lot on bikes as a heavy rider and bikes like to complain with minor noises when I'm riding them.

Best wishes for a fast recovery. I had a kidney stone once it was horrific pain. At the time I had a lot of salads with spinach which is a huge cause I found out. I now rarely have spinach and take a stonebreaker Chanca Piedra pill occasionally just to break down the sediment in my kidneys and...

The trouble with reviews of freewheels is knowing how they are used. If you use it on a conventional bike then they get a real test when climbing hills and if you use them with a mid-drive motor they can be almost instantly destroyed but with a hub motor they can deliver a decent lifespan...

At least it has gears as many similar ebike are single speed. It does have a fixed height stem so getting a good bike fit may be difficult. Sub £300 still a very good deal for what you are getting but not comparable to the value of the ebike of this thread which is 36V and has a much larger...

I think this was mentioned on the hotukdeals thread for this bike and its a common issue for some folding bikes. Fuji-ta is the biggest folding bike manufacturer in the world and also supply a huge amount of frames and forks to assembly plants around the world. They supply brands like Tern and...

That's interesting I thought voltage was directly related to motor speed with brushless motors and current directly effected the strength of the magnetic pull/torque between each movement as it turned but you are saying the same voltage of the battery pack goes through to the hub motor at all...

Really interesting thread. 4A rated controller, 8A peak is even with a fully charged battery at 42V only 168W at 4A. This feels like one of those controllers supplied with 24V ebikes despite being 36V and often used with a very cheap low capacity battery pack, 144Wh or less. The ebike is low...

22mph assistance speed? 22mph sounds great or did you mean 22kph? I must admit I hate a basic cadence system like this. I much prefer a simple throttle where I can just operate when I need assistance it increases range and therefore extends the life of the battery pack. I can ride as much as...

I'm quite impressed with those water proof connectors on the original controller, Is there a spare connection for a throttle to be added to the original controller?

That sounds perfectly normal to me, from the controller output, voltage is speed and current it torque so as the bike slows the controller should start lowering the voltage output and increase the current output to give you more torque assistance but at a lower speed (voltage). It certainly...

Well as Argos are UK based importer they have to adhere to a rigorous certification process so have to obtain the correct certification from the manufacturer which likely needs to have been written by a proper independent certification house and they keep those documents on file in case of...

I assumed the Decathlon figures were input too from the battery to the controller which is more easily measured and just simple DC. Also when you say 12A controller do you mean sustained/rated current or peak/maximum/current limiting figure? I've seen quite a few 250W controllers which are 7A...

8A with a freshly charged battery of 42V is still over 330 watts and pretty sure the 24V folding bikes with low capacity battery packs like 120Wh or 144Wh are only delivering around maximum 120-160 watts of assistance and only about 15Nm torque for some models. It's a significant upgrade on...

Reminds me of when a child asked a woman how old she was and she said '62' and the child responded after a short pause 'I guess you are preparing for death' which the woman was not amused by. I'm not much younger than you I should add.

Not sure its the same Puch Maxi but many years ago my brother had one and when he went off to work I watched him pedal like mad to start the motor off. It seemed like he had to ride half way down the road before the motor would kick in. I used to find it quite amusing I remember. This thread has...

It feels like that weight is because its more overbuilt than many of its competitors which surely isn't a bad thing. Weight is less of an issue when you have assistance anyway. Admittedly it is still about 2kg over what I would expect it to be in weight but there must be a reason for that which...

Annoys me when you see a sticker like that, that states 'Made by Pedibal' when clearly they have just imported a ebike from Asia likely China. There seemed a lot more honesty in the past when items actually said on them 'Imported by' rather than European and US firms pretending they have...

interesting info. I wonder if there is an easy upgrade to throttle as the manufacturer's original version for the Indian market features that? https://www.herolectro.com/h8-112063714_Main.html However I find it difficult to see with Argos's images but it looks like the original Indian version...

I've seen a Jetstream official style ebike. The Jetstream is a just a rebranded fujita bike which I think Dahon has or had the rights to sell in Europe and the US and possibly Japan. https://www.tianjinfujita.com/portfolio/hanma8/ However I did see the Hanma8 rebranded and as a ebike and I...
