    Fat tyres & springy suspension sap energy & speed

    Not news I know, but I wanted to share what differences I've noticed in my bikes, one electric one not, when pedalling unassisted: MTB: springy front suspension, fat 26"x1.9/2.0" smooth tyres speed 13-14mph Torq1: rigid forks, front hub motor, 700Cx38 smooth tyres speed 16-17mph (both...

    suggestions for an updated 'which ebike do you own' poll

    As a follow up to Mary's idea (quoted below, from the current poll thread) to revise the existing poll, suggestions and ideas to make a new poll as all-inclusive, representative and 'future-proof' as possible are welcomed :). Some ideas in the following, please add any more you think are...

    mods (e.g. drop bars) for more aero ride position?

    Does anyone know how hard would it be to modify or change flat/riser handlebars (e.g. for drops) to allow a lower & more aerodynamic riding position, while using a 'thumb' throttle in that position? Is it absolutely necessary to change the brake levers for drop bars as I've read, for...

    Jurassic ebikes test: 50km with 900m of ascent, 18% in parts

    & No dinosaurs! :D Numerous well-known ebikes in this tough test-course: Bionx, Biketec Flyer, Dolphin (aka Swizbee), Ezee, Sparta, Cyclone & Velectris, some with different power motors or models represented e.g. 250W & 500W Bionx, and some on recumbents too, plus at least one tandem! I...

    Rapid charge lithium-iron batteries - practicable?

    How fast might it be practicable to recharge Lithium-iron (LiFe) batteries? I read that they can be charged much faster than most batteries are right now (e.g. with 10-20A chargers, 2-3A being the 'norm' now, so charging at least 5-6 times faster & allowing top-up charges in minutes, not...

    What's flecc up to now?...

    Intriguing yet again flecc! After a total of... nil success guessing your previous exploits, and assuming you weren't being tongue in cheek when you said 'top secret', I figure it might be wiser not to try & guess... (assuming its even possible or likely anyone could!) but although there would...

    Torq 'lookalike' in U.S.?

    Take a look & see what you think - similar styling, power output, weight & two-tone paint job, but smaller 26" wheels, 20mph speed, rear(!) motor, six gears & front sus forks - has someone done their homework (apart from the forks :D)?! Or is it merely a 'parts bin' job? (I'm sure I've seen that...

    How light can ebikes be made? (for a reasonable cost!)

    There seems to be quite some range in weight in ebikes of 26-28" wheelsize available (now or soon): Torq/F-series around 24-25kg, Wisper 905se 21kg (with a larger battery) and Kalkhoff Agattu 20.8kg. I realise some of the weight difference may be due to rear carriers etc., and the Agattu is a...

    An efficient alternative to the QWERTY keyboard layout

    The DVORAK (U.S./English) keyboard layout seems quite logical, efficient & much easier to type on (i.e. less strain due to much less "finger travel" distance) than the ubiquitous "standard" QWERTY, I've found (a quick google for DVORAK keyboard layout should provide lots of information &...

    Torq wheel removal for tyre change

    I followed the very useful instructions for Torq front tyre change & its now done :). When replacing the front wheel a the end, I realised I hadn't noted where the (looks like) washer & spacer go on the left, non-wired side of the axle (sorry if it seems trivial, but I'm a bit of a novice...

    Torq: diameter of replacement seatpost?

    I'm planning to replace the seatpost & am unsure what diameter to get. Those of you who have replaced the original Torq seatpost, what diameter did you get? (If you can remember! I'm aware that flecc & Ian have, and Pete did too). I recall Pete saying his seat post was 25.46mm but the seat...

    Tough hills?.. Get lost?.. Share it here!

    I recently ventured in a new direction towards hillier local territory, for a change, and apart from losing my way (that's the fun of exploring new areas & less trodden routes!), several times, and one impossibly steeply rising section of "cycle path", shortly after an obstacle necessitating...

    hub motor design & torque

    It seems to me hub motors generate torque in two ways: one "electrical" (more copper windings give greater effective current flow past magnets & slow down the motor's ungeared rotation speed while increasing torque) and one "mechanical": using internal cogs & rings to gear down the motor speed...

    Torq owners: What is your top "motor-only" speed? (limited or delimited)

    Hi all, Responses welcome from both limited & delimited Torqers! 15mph is the limited max "motor only" speed and I've read that one or two Torq owners on this forum do get 22mph on motor power alone on a delimited Torq i.e. no other assistance from slope or tailwind etc. so I just wanted...

    Torq: How does the speed limiter work & when best to use it?

    Thought I'd flag up this subject, it may come to nothing but it may also help some find the best use of their Torq for them :). Although I don't have a Torq, it seems many who visit here ride them derestricted, and I was wondering how the speed limiting/restricting is produced on the Torq...

    Can it be done? a hill-climbing & range calculator...

    Can it be done? Ideas for a hill-climbing & range calculator... I realise this won't be everyone's cup of tea, but the idea has been mooted before on this forum, and it may not be as difficult as it seems to roughly quantify these things as a guide to gauging any given bike's strengths...
