Re: new eZip motor

I agree that the lithium batteries are the most expensive component of a budget e-bike build. They represent a significant up-front expense. But that expense should pay dividends in the long run. I also agree that it is cheaper to get a gas motor assisted bike and run it. But personally, I wouldn't ...

Re: Long bike rides!!

I'm still off the bike for medical reasons (more caution than any real impediment at this point). Looks like I may get the OK in three more weeks. It's killing me not riding. The weather has been fantastic here. In the meantime, I've been thinking about doing a long ride from the Phoenix area (Fount...

Re: E-bike restricted trail access and hate

Around here, there are places I'd expect them to ticket people for using the signals and crosswalk as intended, for "obstructing the flow of traffic". :roll: But in reality I don't think they'd ever put them in in the first place. I suspect the only time they even add crosswalks, or traffic signals...

The older a person gets the lighter weight system ( Kit ) a person should get. So a 4.5 kg or less weight geared motor is better in that case. Younger people just do not quite understand this ....

Re: E-bike restricted trail access and hate

Well, you do have to admit that bicyclists DON'T obey traffic laws. I'm not sure what your point is, because here in America neither does anyone on the road, usually with considerably more to go wrong due to much heavier and more powerful vehicles. Also, traffic laws assume that you are basically a...

Re: E-bike restricted trail access and hate

But it is sad that we must "keep the peace" with folks in heavy automobiles, trains, buses etc. who somehow think we should pedal while they don't have to? I don't think anyone says "you have to pedal." Motorcyclists don't, and are 100% legal. If you want to go faster than 20 mph, class three requi...

Re: E-bike restricted trail access and hate

What irritates me about the whole thing, is the assumption that just because I CAN go 30 mph I WILL go 30 mph, all the time, dog walkers and babies in strollers be damned! Right. Most cars can go well over 75 mph which is the maximum speed limit in most states. Some can nearly triple that. I don't ...

<snip> But there is a public relations win when you pedal. It's an easy, low commitment measure to help keep the peace.

Re: Advice please

Thanks Dogman, I like the geared motors in case I have to pedal it and they say they have more torque. Yes, the DD motors are harder to pedal without power - especially if you try to go moderately fast. But you if you have some good low gears, you can make it home OK - just not very quickly. I thin...

Re: Killed hub motor on 1st run, lots of friction now.

Locating the controller where it gets some air flow will make a huge difference in heat buildup. You can periodically check the temp by hand after running it hard to get a good idea for how hot it's getting. When everything is working properly, you shouldn't have to worry about it. Or you could dra...

Re: E-bike restricted trail access and hate

I still fail to understand the reasoning why class 2 is so evil compared to class 1. Same speed, same power level. Just one forces you to move your pedals even if the effort is near zero. I think the three classes are burdensome nonsense that serve masters other than sane e-bike law. IMO, all you n...

Also, it is unclear whether your calculations refer to the use of a single torque arm or two. 1 x 10mm thick or 2 x 5mm. Adjust proportionally, Thanks.

I need to strap some weights on my bike and carry it up and down the stairs to see how much of a difference the two motors would make. Since the motors are only a fraction of the overall weight, maybe the difference isn’t much for large person (6'5" 260 lb/1.95 m 118 kg) like myself. What I noticed...

Re: Aluminium torque plates: your choice.

Good info, and I don't dispute your overall point. Couple critiques of the argument, though. First, 20 Nm at the air gap is... 20 Nm at the axle. Force is multiplied as the radius decreases, not torque. Hopefully Nm vs. N doesn't join Wh vs W in the ES confusion hall of fame. Second, the maximum fo...
