Re: Derestricting motor to 500w - will I notice much difference?

Any speed is down to setting the lcd limit and how fast one can pedal, one will see better acceleration and power on inclines as the max current will be released.

Re: E bike conversion

One needs to say what the bike use and terrain may be.
Hub motors come in various winding speeds or Rpm, for fast riding on flattish terrain then go for a high wound hub. If the terrain takes in inclines then one needs a lower wound slower rpm hub.

Re: Derestricting motor to 500w - will I notice much difference?

Derestricting the wattage probably also allows more current to flow, if so then yes range will suffer.
If the controller is rated as 22 or 25a max then I would think in 250w mode current draw will be 15 -17a and then derestriction will also release more current.

Re: 2020 Tour de France

In the build up today it was mentioned that four teams had one staff member prove positive, now each of those teams now only require one more positive test and they are out.

Re: Gears: are 3x setups extinct?

I picked up a nice 3x front derailleur from SJS for less them £12, the Sunrace model for use with a 48t triple. Fitted it works smoothly and better then the old worn XT model it replaced, for the budget price I'm chuffed with it.

Re: Range of my e-bike.

One battery is 522wh 14.5a/ 36v , the other battery used is 974.4wh/48v so 1496wh. Each battery used independently, the controller is dual voltage and automatically detects the voltage.

Re: Range of my e-bike.

5 miles range is terrible but it depends on the battery capacity rating and the power level used. However your 22st weight is the biggest issue. A typical 10ah/360wh battery is capable of 30 miles or so, if the lowest assist level is used on flat terrain. At 22st though you will not get nowhere near...

Re: SAMEBIKE L026 (folding e-bike 500 watt)

If one thinks 5 miles form anew battery is acceptable then carry on, for my ebike batteries I expect at least 30+ miles dependant on it's capacity.

Re: Cycling and laws

Hello I have been cycling for a year now and so far I like it and want to continue. My shifts will turn to night shifts and was wondering if I absolutely need lights at night time? I really don't want to fit/buy them. Is it against the law to not have them? If I am hit the fault will fall on the dr...

Re: Changing wheel diameter setting

Speed controllers are harder on batteries as they demand /supply max current all the time much like using a throttle only bike. The speeds are pre set, it is unusual for someone to prefer speed control over the much nicer current control models. For flat terrain riding I only ever use PAS1 with my c...

Re: Shimano Steps E6000 battery fail - is it a fuse?

May be the battery is in sleep mode ? One can try long pressing the on switch for 10- 30 seconds. An internal fuse may be possibly blown if fitted, ultimately it probably needs a dealer to service it if possible. The system like Bosch and others uses CANbus so components talk to each other there is ...

Maybe post in the correct sub forum to get answers ?

If your existing bike only does 5 miles then the battery is shagged so needs replacing.

Re: 2020 Tour de France

Watching the live action yesterday there were man places where 30, 40 or 50 spectators were gathered all together in a large group.
Generally most are distancing and today one can see it, though again today with a little over 36.5k to go a group of soles maybe 15/20 strong show no sign of distancing.

Re: Where is the best place to buy an Electric Bike

The UK has additional pedelecs laws that differ a little from the EU, stand alone throttle is not allowed though there is a loop hole that allows bikes to use one if it is operational only after peddling.
Bikes prior to 2016 are allowed them and are fully legal .
