    Amps at the Bike Place - Silverstone, Northampton 29th-31st Jan TRADE SHOW

    The problem with the above post is that, unless you're a signed-up member of this forum and actually logged in, it just appears as a small thumbnail image and nobody can read it. It means that the many casual visitors/readers/followers on the forum here will be deprived of that information...

    Bafang Max Drive bikes

    400ah battery? Blimey, I'd like one of those! You mean Greenway's own 10.4Ah/374w Samsung celled battery... spare batteries costing only £160, which also makes Bosch/Yamaha £600+ battery prices look stupid. In all seriousness, that Greenway bike (E-change cross/city) was previously selling for...

    The best legal ebike kit

    I take your point. My bike (same model as yours) is marked exactly the same way (except mine is a later batch). It's because the bike seems ridiculously cheap for what it is that I spoke to the owner of East London Bike Co (who owns the Greenway brand), who double-checked with the makers, and...

    Your earlier photos did show some rust and corrosion, which did seem a bit unusual given the bike was only 6 months old. Glad to hear you bike is now fixed.

    Is 48-volt the new standard for 2017?

    Ah yes... good spot. I was looking at the current/official Max Drive Dealer Installation Manual for that drive system, and there's no mention of a 48v option. It must be newly added. But even there, they don't mention a 48v 350w variant, which is what the Chinese are now offering on this new...

    Is 48-volt the new standard for 2017?

    I don't think that is what they mean here... the Ultra is 1000w and looks different. The current Bafang dealer manual says the Max Drive is available in both 36v and 43v versions as both a 250w and 350w variant. This says Bafang II 48v 350w (i.e. Bafang MkII?). Here's a pic of one of the new...

    Solar charging..

    Yeah... except the subsidies have recently been substantially reduced. When I first enquired it was worth doing cost wise, but by time the planning permission came through, the payback figures just didn't stack up anymore.

    Is 48-volt the new standard for 2017?

    I’ve just been looking through a couple of the new range 2017 Chinese e-Bike Factory catalogues... the kind of e-bikes some of our UK importers have re-branded and then sell here as their own models. In last year’s 2016 catalogues I noticed ALL the stock designs were 36-volt... ranging from the...

    Solar charging..

    I’ve looked at this before too, but never found a satisfactory way of using a solar panel to charge the bike battery directly. Li-ion needs a CC/CV charge, and a modest solar array can’t deliver the amount of power needed... and the power generated is erratic (due to fluctuating light levels)...

    How to true an electric bicycle hubmotor

    Thanks for posting that SW. I've always seemed to make a hash of it in the past, but using that method, I've just "trued" 3 wheels which had irritating minor deflections and it works brilliantly!

    Why doesn't Pedelecs do more E-Bike reviews?

    Yes, I too agree. But I think many would accept that any individual reviewing their own ebike would understandably be positively biased towards it (unless - despite having weighed up their own needs and then parted with their own hard-earned cash - the bike then turned out to be a real dog). And...

    The best legal ebike kit

    I've had my eye on one too, and had already spoken to them to confirm which Bafang drive it actually is. They checked with their "Taiwan Engineer" and confirmed its the 330.250 Max Comfis with the 07 display.: http://www.szbaf.com/en/drive-systems/drive-system/max/max-comfis.html It's not the...

    Battery DIY.

    I broadly agree (I have an original and a clone)... some B6 clones are reported to have issues with resistor tolerance meaning individual cell balancing can be a little wayward, whereas the Sky-made original is spot on. The other limitation (for both versions) is charge limit is for 6 lithium...

    Full carbon E-Bike thoughts?

    Wow! That was really interesting and for me a good education in Carbon frames. I've noticed a couple of the Chinese low-end e-bike "fodder-factories" starting to offer Carbon frames as part of their lower-cost e-bike offerings (much lower cost than the German and Dutch makers anyway). If even...

    That's a totally different problem with this specific e-bike, mentioned on a few threads here, but well documented on Halfords own site. It seems the battery jiggles around a little in its' bracket breaking connections - using a strap or Velcro pads to hold it firmly appears to stop that. Back...

    Yes, according to Suntour's own website, it's Infra Red, and a part of their own ATS system here: http://www.srsuntour-cycling.com/e-bike/ats-rear-motor-system/ There're instructions to download there (although out of date) but sadly no troubleshooting or maintenance help for this issue...

    It might be the cadence sensor on/under the crank misaligned or broken: The sensor detects pedal rotation from the magnet disc and needs to be fairly well aligned. Or run the bike back to Halfords for a quick check over?

    ebike theft and precautionary measures

    All this talk of rampant bike theft has encouraged me to add my newer e-bike to the immobilise national property register so at least if it does get stolen and later found, the Police know who it belongs to. The immobilise site suggests that after laptops/tablets, phones, jewellery & cash, a...
