Re: Accidentally left Cycle Analyst on overnight, drained my batteries to death?

No Shame, I have done this before as well, just dumped the lipos and bought a new set, as others have said a BMS or battery murdering system as I normally refer to them is not required, back in the early days of lipo testing 12 years or so ago all of the problems came from BMS failure, ive been runn...

Re: Sur-Ron - New Mid drive Bike

Any machine with an electrical system that’s non homologated falls under the U.K. and EEC machinery directive for EMC and electrical safety regulations So the bike must have the correct CE markings (not EN it’s not a pedal cycle) and technical safety file Otherwise not only is it illegal to import ...

Re: Sur-Ron - New Mid drive Bike from China

Yes cant be sure if Luna will offer the same terms so its worth checking before you part with your money, its a super exciting bike thats for sure, early adopters like Hyena and his mates will give this thing a good test and there are a few moto crossers who have got their hands on them too so thats...

Re: Sur-Ron - New Mid drive Bike from China

Hmm there maybe a reason Luna isnt posting warranty details yet because if you buy the bike from Luna isnt the warranty going to be dealt with by them? do they have to offer the same warranty that the factory do? and if you buy the bike from Luna the factory wont likely deal with the end user for wa...

Re: Sur-Ron - New Mid drive Bike from China

why do the peddles need to actually do anything? ive been riding ebikes on the road for 20 years, in all that time I have been stopped by the police once (and I ride my bike every day to work) in most of that time my bike has been going so fast that the peddles make no difference I simply move my le...

Re: Sur-Ron - New Mid drive Bike from China

How longs a piece of string? from what I have seen the chain is well capable, belts are a weak point esp when being used off road, I expect this to be a weak point in the transmission over time, esp when being hammered off road, its not a deal breaker for me though.

Re: GCinDC's Giant DH Comp

Hate to say it but I just have to, if you are going to ride at those speeds you should start obeying traffic laws as any other vehicle. They will be scraping you off the road sooner or later if you keep that up. Besides that, this is why ebikes are going to be legislated against real soon. Your new...

Hi Kev halving the voltage will double the ah rating at 24V but you will still have the same watt hour rating and effective capacity, it will also have the effect of increasing the current through the cables hence the warming of the cables that you found, doubling up the batteries though will help r...

Its really very nice indeed, the SLA batteries will sag like an old tit and will get worse quickly I know this from experience. There are loads of threads on here about building packs, at 15KW you are going to need a pretty decent pack to feed this, you could do it with model Lipo in parallel banks,...

Yes been watching Troy on Glympse (that’s so addictive) and am just amazed at the miles that he has been popping in on that bike on a little old golden motor too that has already had about 8,000 miles put on it! Troy is doing what we all dream about doing or talk about doing, the xtracycle is a grea...

Hi Troy This trip sounds like a tall ask in the time that you have to do it and there is no shame if you can’t quite make it either, it is a very very long way, easy to do it over here in the UK as at its narrowest point its only 200 or so miles, so that would be just a couple of days out of your s...

Nice Bike! I have been running macs and BMC motors for years (nearly 10 years) , 2kw is the sweet spot, anything over that and you will quickly blow the one way bearing in the freewheel or rip the teeth out of the gears, riding style also matters as you have found out, nice smooth assisted starts an...
