Re: High power ebike means none of the rules apply to me

Sounds like most who commented aren't concerned with any rule changes in the near future, so that's actually kind of heartening to hear. You have to consider the crowd. Who expects legislation to be based on what we think is sensible? Even "our" advocacy organizations, if PeopleForBikes qualifies, ...

Re: two way throttle? (thumb or twist)

All the diy built bikes are using mechanical braking and no regen? Rediculous. No, a direct drive build without regen is a pretty near the bottom of the barrel. (But direct drive only - hubs with internal freewheeling gearing don't do regen, nor do crank drive builds like BBxxx.) But I believe most...

Re: Lime Bike battery fire

There's a pretty fair constituency for them here, I think, so it isn't just down to city hall to twist their arms hard enough to clean it up. The city has to make at least a show of bending over for Lime et al., so they can cultivate the young people vote (not that these young people really vote ver...

Re: Hub motor industry dying?

By the time you make the hub big enough and rim small enough to be capable of climbing you've destroyed any ability the suspension has to operate on rough terrain. So off road , hubs are at a disadvantage? I'll take your word for it. I suppose the Chinese, who supposedly account for 90% of electric...

Re: Hub motor industry dying?

Drivetrain damage with a mid-drive is 95% related to the technique of the rider, hub melting is 100% related to design and environmental. You can learn to use a mid-drive, but you can't magically dump heat from a hub. I think there are many of us, though, for whom that melted hub is not real. I mea...

Re: Hub motor industry dying?

After all of those compelling reasons for using a mid-drive with an inrunner or outrunner, why should hub motors exist at all? As it turns out, a lot of people don't want or even know they can do better with a mid-drive solution. They hear you need to maintain a mid-drive (lube the chain) and are i...

Re: ebike laws with trike build

you cant have both rear wheels drive without differential . Sure you can. You just end up with scrub on one of the tires in a sharp enough turn.

Keep in mind that this can be a very "tippy" trike, so you may have to slow to walking speed (or less) for any kind of turn, or end up on your side
Any kind of turn including unplanned emergency turns.

Problem is if an accident happens because there is no insurance. So if you hurt someone badly costs can go into 100.000nds of Euro, even above 1 million. You have to pay that out of your own pocket. This is very bad either for you and for those person you did hurt. I assume the concept of insurance...

Where bosch is heavily lobbying, is to have their motors pass certification. I repeat it again and again: there is no way bosch active line or cx line are 250W-continuous limited.

Just following along at home with no electronics expertise or expectation of ever using this stuff, but I wonder if the switch needs to be so complex? The variable ebrake I guess is to be homebrew, with a 4V neutral up to 0V max pot, so you double it up with a cutoff switch and route the throttle po...

Re: RadPowerBike RadCity Commuter

We're going to find out about the limitations of this commercial ebike. The big standout today was how slow it was on the local hill. It is rated for 750 watts. Lots of ebikes will temporarily run more power, perhaps that's why this feels slow. It may be 750 watts peak rather than average. Right - ...

Re: Ok, so I crashed again today...Is it time for a trike in the city?

The California code does not say "no throttle" from what I found in their code. Either the online resource I used is out of date, or this is more misinformation on this subtle distinction. No, thank you, the same on California's own site, http://leginfo.legislature.ca.gov/faces/codes_displaySection...

From Bosch website The three classes are defined as follows: Class 1: eBikes that are pedal-assist only, with no throttle, and have a maximum assisted speed of 20 mph. Class 2: eBikes that also have a maximum speed of 20 mph, but are throttle-assisted. Class 3: eBikes that are pedal-assist only, wi...

Re: Ok, so I crashed again today...Is it time for a trike in the city?

Speaking for myself, if given a choice between a "bike lane" divided from road traffic by only a painted line, and a sidewalk, even a busy one (which I only rarely experience), I'm going for the sidewalk option every time. I guess if it gets to that point for me, I'd have consider that it's time fo...

LiCo is the most dangerous chemistry. Is that because LiPo is too rare to be an issue? Aren't 90% of the incendiary accidents LiPo?

It's way more dangerous to cycle on the sidewalk unless you are going walking speeds. For me, that's largely about intersections, where I suppose your really significant chance of trouble awaits. Riding out in the street, there's cars and trucks whizzing past and it seems hazardous as all get out, ...

I read that for example the Germans bought 1 million electric bicycles last year, about a quarter of bicycles sold, and similar story in the Netherlands etc. At this rate practically everyone in Europe will have one. Are they all running cords out to remote outdoor charging stations?

Of course if the US took my suggestion and made a new class of drivers’ licenses for light electric motorcycles, vehicles like the UBCO FRX1 might be easier to register and ride on roads without needing to act like bicycles. Of course you'd never be able to legally put this thing on the road as som...
