I'll let someone else talk about rewiring if they'd like but this is a "emergency" technique since we do have softer kick stands.
The problem there is that it takes more side room than using a reverse gear. IMO, all electric bikes should have a reverse gear, as it's usually very simple to just add a switch and wire and very little other stuff.

That's true and I agree but like your Energica also has software to limit your speed to a safe very slow speed.  So a little more involved but yes it would be nice.

Of course on a long super tight dirt track reversing down hills and around other obstacles means bad news is likely, so just having a reverse won't fix all of the problems.

Shouldn't  be more complicated than have it switch to the custom mode with very low values when in reverse.

But with the good slow speed throttle response on Zeros in ECO mode , IMO, just forcing to eco mode would be good enough for a  reverse.

The unofficial manual has a write-up for this based on this thread and my own experience on the 2016 DSR which Hollywood Electrics enabled: https://zeromanual.com/wiki/Gen2/Implement_Reverse_Mode


I really enjoyed having a reverse mode, particularly since my house is on a slowly subsiding side of a hill so my garage floor is uneven and the side street in front is extremely uneven. It's good to hone your technique and skills, but the assist is really helpful, and probably even more while on trails.

What does this mean?

"Recent Zero models (2016? seems IPM-related) have a glitch when reverse mode is configured using the standard Sevcon recommendation."

Does that mean the reverse cannot be added to 2017 and later models? What is the "glitch" ?

It means that it can, but you need to use Sevcon's DVT tool to apply a custom profile (DCF) to get it to operate correctly.

With the naive non-IPM profile on my 2016 DSR, we performed a wheel spin up test and found that after a second or two in reverse, the wheel would "hunt" or "toggle" gently back and forth. It was conflicting with another configuration parameter.

I have a copy of it for reference but have been unsure whether to share it per se or how to document the workaround reasonably.

Zero could probably sell a few more bikes if they add in a reverse. That was one of the main reasons I purchased my Energica.

But now that I have found how useful it is, I want it on all of my bikes! Normally not needed if one is careful where they park while riding, but sure is handy to back in and out of the garage when the very start of the driveway is on a hill, as it is here.

I agree that Zero’s models would be better and sell more easily with the reverse feature, but every conversation I’ve had with Zero people has been myopic. I cited the Energica functionality to some who weren’t even aware of it.

Every time I visit Zero headquarters, some employee doesn’t even recognize my aftermarket fitments like the Madstad screen. I wish Zero people would show a little more curiosity and awareness.

In the end, I own the bike I can fix and make work for me and others.

That had "zero" impact in me buying one.  If they had competition from a dozen other brands, then maybe it would raise an eyebrow.

This is not about you or others who bought a Zero. It’s about what factors Zero might be ignoring that might increase their appeal.

The bikes would instill more confidence and affiliation if the manufacturer attended to some features to make the bike easier to work with.
