Electric bike charging
Thinking may get folding electric bike x 2. Would there be ample power to charge batteries whilst we are connected to the mains on site?

yes, absolutely no problem....we use ours all the time.

Hi ipt, we got our two corrara cross city folders two years ago they are brilliant and don't use much power to speak of charging, a small hint keep them charged when its cold in the winter and bring the bateries in doors cos they can go into a thing called sleep mode, I even have a trailer for" Noodles", that's him in my avatar, your never regret it..

I'm trying to work out how to charge them when off-grid. I suspect the prolonged time on an inverter that recharging bike batteries require would not really work given that it is a 2 amp draw.

I thought an ebike could be charged by pedalling as opposed to coasting on battery. It seems odd that you can’t charge on the hoof so to speak🤔

No but you have to pedal cos they stopped throttle type e bykes for some reason, I get around 25-30 miles on a charge a bit less with the dog with me , because they are Lithium batteries you can charge at any time reguardless of how much its showing on the guage, Halfords guarantee the bateries for three years which is bloody good cos they cost £250 to replace..

Thanks👍🏻. They missed a trick there, they could carry the ‘save the planet’ precursor if they could be pedal charged.

I believe 'they' are working on it but at the moment the necessary equipment would make the bike so heavy that you wouldn't want it anyway.

No, but the more you pedal and use lowest settings, the further you can go. We seldom get out of lowest level if out together, but if OH is out on his own, doing something serious, Yorkshire hills, then he has to use higher electric power (cannot let his heart rate get above a certain maximum). Usually, even on a stiff ride, he can do 35 miles just using power to keep his heart rate down on hills. He did a ride round Tintagel and Boscastle coast using some narrow Cornish lanes last year. The inclines meant his battery was drained after under 20 miles. It’s all about doing manually what he can safely, and using power assist to monitor heart rate. E bikes have been brilliant for serious cyclists who have heart events, means they can still enjoy their hobby. My OH has some really nice none electric bikes, so he went down the route of building his own power system into bikes. Sourced all components via Chinese eBay (most batteries and fittings come from China) and built himself a motor into his crossover road bike. Battery is bottle sized fits into his drinks cage. Total to put motor on, including throttle, £450. That’s onto a bike worth many thousands. To do my nice off road bike cost £350. There’s a forum called Pedalecs dedicated to all bikes electric. 😁

CY, I've certainly done mine on a 500w inverter....although best to do one at a time (mine has a longer range than OH so needs charging less often) and in sunshine if possible to keep the batteries recharged.
its a balancing act though, as a 12v system charging a 36v system via an inverter is 'expensive' on juice.
i did read on another forum that Aandncaravans (the charger repair specialists) are developing a 12v charger (with an array of output pins to fit all bike batteries) that will do away with the inverter and the associated losses...

It's quite an experience staying on a Dutch site. Both sites that we stayed on last year had Barn areas filled to the brim, each with a charger for the clienteles' bikes, provided by the site owner. Both FOC.
Also served as a locked storage area overnight.

Almost every battery charger these days is a switched mode design. These depend on having a smooth sine wave input to work properly - if at all.
Inverters vary in what they produce. The bad ones just produce pulses of alternate polarity seperated by no voltage. The good ones do a close approximation to a smooth sine wave. The blurb that is used to sell inverters often has some weazel words about the output to try to bamboozle the buyer.
As a rough check - if the inverter will run the microwave with a similar heating effect to normal, and without weird noises, then it is producing a good approximation to a sine wave. That type would be safe to use with a switched mode charger. The more brutal ones cause the transformer in the charger to overheat and the capacitors to fail prematurely.

Good posting as it is, in nontechnical terms, it makes the point many inverters will simply wreck your very expensive charger that came with your e-bike, and probably the inverter itself.
These e-bike chargers "typically" require power exactly like as comes out of an EHU.
Only some inverters create that, again "typically" the very expensive high quality ones, certainly not the budget end models.
