Re: I saw a park ranger call out an e-bike rider on FL bike path.......

I had to get a Doctor's statement to apply for a Disabled placard for my car. I carry a copy of that letter on my e-bike. I haven't had to use it yet, but I hope it would carry some weight if I did.

Re: I saw a park ranger call out an e-bike rider on FL bike path.......

So here's a question, that for me kind of gets to the point of "pedal assist only." Are they (any of them) adjustable, so that the slightest pressure will get the motor going? The pedal assist version of a super low granny gear, even so you could practically mime pedal? The super low gear (which my...

Re: I saw a park ranger call out an e-bike rider on FL bike path.......

The problem with PAS-only laws is that they make it hard for disabled riders - the ones who benefit most and most legitimately from e-bikes - to ride. If I had to pedal that first crank revolution unassisted every time (especially crossing roads and highways) I wouldn't be able to ride as much. A de...

Re: Rear Hub or Mid Drive for general XC riding?

There is a significant difference in power between a mid-drive and a hubmotor of the same power rating. Geared hubs close the gap a bit, but then you have plastic gears to wear out. If you want power get the mid-drive. If you want simplicity and ruggedness, get a gearless hubmotor and be prepared to...

Re: New 52v battery sat unused for two years...

But if I assume the BMS has a 50uA drain and the guy did not lie about the 2 years duration, then 50 uA = 0.05 mA = 0.00005 A (of BMS draw) So in 1 hour, thats 0.00005 Ah drained out of 28Ah So in 1 day, thats 0.0012 Ah So in 1 year, thats 0.436 Ah So in Two years, thats about 0.9Ah ...

Re: TSDZ2, how do I know I'm not wearing out the motor?

One thing you can do is get an inexpensive stick on thermometer with a second temp sensor probe on a lead, and stick the "outdoor" sensor onto the part of the controller that gets warmest. That would work. Do other riders worry about this problem? Or am I over thinking things having only just insta...

Re: I bought a used Chevy Volt - and you probably should too!

If subaru made a PHEV we'd likely look at that. AWD plus cargo space is a critical requirement. Subaru just came out with a PHEV that uses the Prius Prime ICE and battery, and a Subaru drive system. It has, IIRC, a 20 mile AER range. Though, I'm curious - which 120+ mile range BEVs are you referrin...

Re: I bought a used Chevy Volt - and you probably should too!

Just to be clear, I'm an EV proponent, and with many 120+ mile BEVs available now, a PHEV isn't my cup of tea. I'm just saying that the Volt is a more special use case than the OP implied: it is best for those who have to make 150+ mile trips regularly, but who still mainly drive less than 50 miles ...

Re: I bought a used Chevy Volt - and you probably should too!

You correctly note that the Volt doesn't do very well as a plain hybrid once the charge is depleted, but you neglect to mention the plug-in hybrid that does fantastic as a hybrid once the EV charge is depleted: the Prius PHEV, aka "PIP" (Plug-In Prius). The PIP, which was the forerunner of the Prime...

The only way that battery could possibly be ok would be if the BMS was disconnected at the factory and had to be connected by the purchaser. Ping Packs came that way.

Re: which battery type is best?

As already noted, you seem to be confusing chemistry with packaging. Many (but not all) of the pouch cells are LiFePo4, which is very stable and long-lived but has a low energy density. Hmm, I've used pouch cells a lot, from 1.3 amp hour to 13 amp hour. I've never seen a LiFePO4 pouch cell, nor hav...

We were in fact all telling you that it was a front alignment or suspension issue. There is no sensor that can cause torque steer.

I'm a moderator at mynissanleaf.com (where you may want to repost this). We haven't seen any sudden or inherent torque steer issues with the Leaf since it was first introduced. Torque steer is almost always a design issue having to do with axle half-shaft length - it doesn't just suddenly come on. I...
