But a nonsense element included, since there is a standard 10% tolerance on all UK speed limits, this confirmed by the DfT. So the lowest of the recorded speeds do not count. This is typical of so much conflicted recent legislation, ill-researched before being passed into law by parliament. .

There's been many attempts at these over the years, one of the ideas that just keeps coming back. Always the same control problems though, not just steerig and balance but the way the human/mechanical load lags or leads during acceleration or braking. I can imagine the fore and aft pitching...

No! :eek: .

I wouldn't be too confident about that, insurers are notorious for attempting to dodge liabilities. Even a small bike shop can have some liability insurance which might be underwritten by a large insurer capable of big payouts. .

Just like the power question, the e-bike law isn't quite so cut and dried. Firstly, "private land" in this context hardly exists. Anywhere where the public have access to is subject to the pedelec regulations so, since the right to roam legislation was put in place, we're largely only left...

Yes, the "n" in and, where you've used an "m" instead. ;) .

Who knows, the Caribbean countries might join the EU. After all, Hawaii joined the USA from the other side of the Pacific. .

Same here, growing up through the days of food rationing, my nickname as a little kid was "tin-ribs". Shirt off my ribs were a good imitation of a xylophone. Wasn't until my army days that I got some cover. .

Not necessarily, that quote was about power (Watts), not voltage. If the increase in voltage was accompanied by the same Ampere hour capacity, then the wattage is increased. That can be used how you wish in two ways. By gentle riding for more range or aggressive riding for more performance...

I think where this comes from is that if one increases the voltage on a given motor/controller combinatioin, the speed increases pro rata. For example on a 24 volt bike, change the 24 volt battery for a 36 volt one, which is 50% higher voltage. Assuming the controller can accept it the speed...

It holds more power potential. Power isn't current or voltage, it's the multiple of those, V x A = Watts. So your examples are 900 Watts against 720 Watts. One is 25% larger capacity so can do 25% more work. You can choose to have that extra work performed as range or speed or hill climbing. .

Not much in it in that idealised condition, but that's rare. In practice there's likely to be some acceleration periods, slopes, head winds etc. all of which giving the more powerful motor a chance to show its advantage and consume more. .

One disadvantage is that you're lugging all that huge extra weight, even when you don't need it, affecting the handling and cycling pleasure. And if you break down, you'll curse pedalling that weight back home without power. A dual battery advantage is that one can be on charge while the...

As I said, it depends on their speed speccs. If both are similar 30 mph motors, then the choice is between better hill climbing with 1500 watts or longer range with the 1000 watt. .

Carrying a spare battery is a good option for longer/faster trips. I've even done runs with three batteries. .

OK, 30 mph is a good start point. If you aim for a hub motor that's specced to achieve 30 mph on a stated voltage, a higher wattage version if there's a choice will give more torque. So that answers your original question in one respect. Regarding your listed options, since you can't do it...

No, the position is more complex than that. Your original question isn't answerable in that form, it depends on the design brief and motor type among other things. The 1500 watt can be a little faster and have a little more torque combined, or it could be just faster or just more torquey than...

Of course, Mars fault for opening their largest factory at Veghel, The Netherlands and shifting the majority of production to there from their traditional home at Slough. It's Cadburys all over again, and the prices of their products will rise too. .
