Been using this one for a week or so item.mobileweb.ebay.co.uk/viewitem?itemId=181161657311 Not the cheapest but it's in a hard case so can take more abuse than the PCB only versions It's also easily loud enough to hear whilst moving at full speed and wearing a helmet (snowboard one) . I've...

The handlebar led are not very good indicators - when the motor is pulling high amps (such as going up hills) the voltage can sag. This causes the lights to drop out. Stop for a few seconds and they all come back The indicator on the battery itself is better

www.dynamicbicycles.com/chainless-technology/shaft_v_chain.php Apparently shaft is 90% and chain is 75% to 95% !!! Id struggle to make a chain only 75% efficient even I I tried !

Has it always done this since conversion ? Or a new thing after plenty electric miles ? Is it progressive in line with braking? I mean gentle braking = gentle judder and heavy braking = heavy judder

Hmm, try 1) check to see if new rotor is warped or has any chips in it 2) stand over bike and with the front brake on, rock it back and forth - any play mean the headset needs tightening

My latest understanding is these are multiple safety features. The charger will stop when any one of the following conditions is met 1) 5000mah has been delivered 2) 2 hours has passed 3) the voltage of the pack has reached maximum If you press the right hand arrow button during charging it...

We don't really to worry much about the greater inefficiency on ebikes ! Seen to remember reading 99% for derailleur and 85% for shaft ?

I'm new to these funky chargers and still have lots to learn Which is a roundabout way of saying - what do you mean please ?!

Here is my version (for non engineers like myself - I know this is oversimplified at best : ) Acceleration is the word that describes increasing your speed over time. Example, get on your bike and go. In the first second you are travelling at 3mph , in the second 6mph, the third 9mph and so...

Thanks as ever I got a power supply with it - gave up trawling the local car boots ! Ahh, so the cutoff is for the amount of ah you expect a pack to take - not its actual capacity . So if my 10ah pack is half full then cutoff at 5ah is about right Noted about the balance. Seems like if it's...

Sorry to put here - I don't have rights to post in technical :( I just got this charger through the post - on d8veh recommendation (and others ) to charge my booster packs. And ultimately my lipo packs which I will buy when my BMS -bypassed bottle battery eventually dies Ii have a couple of...

It is possible the brakes cutouts are faulty or have a bad connection. I don't have a cyclematuc . Can you trace the cutout wires back to the controller And unplug them? If the bike then works you know they are the issue I have spare ones from an 8fun kit you can have if you need Cheers...

This looks fantastic ! Love it :)

Bit of background - my dad is a lifelong senior service smoker. I want to get him onto ecigs. He is not keen but I get the impression he just feels and looks silly. So I made him this - its a vintage senior service tin with about 3800mah of batteries. Rechargable via micro USB and has a...

Ok, well d8veh supplied cells tested this morning- the grin is back :) does 24.5 no load hot charger. Did 22.5 in real world unassisted dropping to about 21.5 after first mile or two 4 personal bests on Strava of 5 segments (tool it easy on the first one) 7 miles later I have 7.95v on booster...

Hope you can make sense of post! Fat fingers, small touchscreen and a train to blame for endless typo's! :)

welcome :) ok, first off are you pretty with bike mechanics and basic electronics ? (by which I mean simply testing voltages and a bit of soldering) if yes then a kit could be a winner for you, if no then you could get a compy like Cytones to convert your wifes bike. Usually around the...

Made the new pack using d8veh cells I decided against 48v as carries risk blowing things up. And I quite happy with performance at 44.4v So made a 2s6p 7.4v pack which lives in saddle pack. Xt60 connectors to controller ad balance leads. I have ordered a female 2s balance lead socket as it...

Well I was going to replace my 7.4v pack. But why not go higher :) Thanks again , will report

This first pack I am soldering up as the previous one came ready made BTW !
