Bathroom shaver sockets are deliberately current limited to save you electrocuting yourself if you were to drop your electric shaver into a basin full of water. You can either cut the plug off and fit a standard UK one with a 3-amp fuse (B&Q), buy a European to UK plug adapter (B&Q or most...

It was the Greenway Cross City for £1000, which had a 350w 80Nm Bafang Max-Drive, pretty standard Shimano 180/160 hydraulic brakes and 9-speed Altus gearing, Samsung battery pack, and Suntour NEX forks on a Chinese frame. I bought one, as did maybe 5 other fairly vocal members here on this...

Hi Phil and (guessing there aren't too many members here from Beds district), welcome! I do the old railway Sustrans route 6 from Welwyn through Luton up to Leighton Buzzard now and then... with diversions up and around the back of the airport via the Plane-Spotter camp, Kings/St Pauls Walden...

That's a nice map - a true labour of love it seems. The Atlas though highlights which of those old/dismantled railway routes has now been converted into proper cycle tracks, and where old stations still extant on those routes have been renovated and/or converted into B&B's, cycle hire, and/or...

AFAIK the newer purpose-made car jump-starters use Lithium Phosphate cells to deliver the high current burst required... 4 cells at 3.3v nominal in series to give 13.2v. The cells used are typically only 25-75Wh... not big at all, but just enough to provide that quick burst of energy. These...

I find this is invaluable for identifying old railway routes that are now converted to cycle paths all over the country: https://www.amazon.co.uk/Railway-Atlas-Smith-Keith-Turner/dp/0711036950/ref=sr_1_3?ie=UTF8&qid=1522615142&sr=8-3&keywords=railway+atlas+then+and+now Also, most County Council...

You're missing the point entirely. Your German bike isn't German at all. It's a product of Global manufacture... just with an inflated German price tag. R&M are as German as Woosh or Amps bikes are British. I am half-German by the way, so have no axe to grind. But hey. delude yourself if you...

Well, that sounds to me like a great testament to the quality of Far Eastern manufacture given the bulk (probably all) of your Riese and Muller bike is actually manufactured, if not assembled, there. All we seem to be missing is the opportunity to pay the poor Far Eastern factory another £50 to...

Various comments I’ve been reading lately on this forum: Kalkhoff are probably the most unreliable e-bike motors available. Bosch motors are made in France. Riese and Muller use Taiwanese frames and Cube frames aren’t made in Germany either. Given that almost all of the other bits screwed...

I’ve spent many hours trying to recover numerous lead acid batteries over the years, using various methods like salts and electronic high-frequency “desulphators”. Sometimes you can extend the life by a year or two, but I’m not sure it’s worth the time invested. Most lead-acid batteries die...

The USP (unique selling point) here seems to be that the Polini motor is lighter than the Shimano Steps motor, yet has the same torque at 70Nm. Bosch is quite clear that the weight of their new motors directly correlate to the number of copper windings... the higher torque Bosch motor has a...

This guy suggests changing that 1k pot to a 5k: https://www.yousun.org/archives/398#more-398 I've seen so many circuit variations of this "same" Sans SSLC084V42 model charger now I'm beginning to wonder if any two are exactly the same... but the caps are always only rated at 50v which might be...

The largest group of independent mobile bike techs in the UK are Cycle Tech - each is an independent operator (it's NOT a franchise), but shares common branding, work standards and ethics, access to bulk-buy parts, shared knowledge etc. I'd think it's a good place to look if you're considering a...

Two of my local bike shops seem like a hang-back from the 1970's... in both appearance and attitude - and very limited bike stock that best suits that era too. And neither has a clue about electric bikes. I think this kind of LBS is the future: It's in a van. A man (or maybe a woman?) who...

You have answered your own question... there are two ways of answering the OPs dilemma: You can use an Invertor, or a DC to DC convertor. Both have advantages and disadvantages. Stored power in an off-grid mobile/camper situation is precious, but the less efficient method has some advantages...

I do agree with you. But when even a basic camper van costs upwards of £40,000, is £100 really an issue?

There you go then... confirmation. I've just got back from my holiday home in Norfolk, and just checking my own SF-03 charger: The box (and charger) look identical to the normal Halfords/Phylion SF-06 charger, except the charger has a different model number, and the box has a sticky label on it...

Mmmm. I do get both arguments... Yes, the MPPT/7210 idea is more direct and has lower conversion losses, but... Your 7210 at £28 weighs 480g. The Bestek 300w pure sine-wave inverter costs £40 and weighs about 600g. It's physically not much bigger either. I personally do also have an MPPT solar...

The Crossfire-e battery is a Phylion SF-06 battery with the same connector/charge parameters as the Phylion SF-03. So I would say insportlines SF-03 charger should work fine... but it would have been nice if the Devron seller knew enough to confirm that.

Looking at that sellers website, Devron e-bikes use several Phylion battery types, including the SF-03, SF-06 and SF-06s. The 5-pin round connector used on the SF-03 battery is exactly the same as the SF-06. The voltage, charge rate, handshaking, overheat parameters for both batteries (checking...
