    hmmm... café racer pedelec?

    Like the styling - is that a zforce motor or an updated Mars?

    Just an FYI in case you're not already aware and in case any future thread visitors decide to try this with any old PSU.

    What makes you think that?
    Any DC power supply which is clamped to the pack Vmax in voltage terms (so in your case about 110-113V) , and has current limit enforcement built in, will bulk charge a...

    Showing your age there Richard. :p

    It's a similar layout aesthetically to the Ariel ace; but (and conceding that I didn't get to sit on it) the actual ergonomics look more akin to any modern...
  13. Finally then the honorary mention - Veitis

    The Veitis is basically similar to what most of us on here have already built to some degree except this one has a £40k pricetag and a very nice wrapper.

    Dunno about that notion dude.
    With the weight of the chain and its velocity at even relatively slow speeds, I expect it'll just be a mess - you'd be better staying as you are at that stage.
