TM4 TautronicTM | Dana TM4 Claims to supply the inverter to Zero motorcycles. Maybe the new SRS bikes? I think all the older models use sevcons... Also to address my own curiosity, this was the only place i found selling the sevcon software (didn;t try Borg Warner directly though)...

I'll go in on a ixxat with anybody if its prohibitively expensive I'm wondering if two votol 150s controllers might work on a split stator motor. I guess you can modify the shunt inside and trick it into dumping more amps. i think they might be voltage limited though. cheaper to experiment...

So far I think there is only the one bike made? I recall a comment by others that it was a husky chassis from a few years back. (pre ktm engulfment)

The controller they show is one of these SL controller series | siliXcon I think this controller brand is also used in Cake and EM

hey great, small world! send me a message with your info or post it

closest big town to us is winchester va

I have a dealer laptop if you want yours checked or updated

go check out the banshee storm! maybe its not that far from you? https://naticycle.com/ols/all?page=1&sortOption=descend_by_price

Zero motor, BAC8000, big prismatic battery? HONDA CRF 250R Električni Motocross - BULL BIKES Električna Kolesa

How many LED are possible? It sounds like so far you have one for state of charge and one for error/contactor closed. If the arduino? has access to all hundreds of data parameters then there are a bunch of cool things that people could make use of eventually. Battery temp seems like it would...

This is great. If you build a component that allows the bike to be functional without the ALta display, you have a winner. As for the added indicators, they are gravy. In deciding what gravy features make sense, can you give us a menu of what might be possible? The alta display gets...

How can a bike weighing the same as the Alta go further with a smaller pack of the same cells?

More frankenbikeism. Changed from 19 inches front and back to 18 and 21. Let's me use taller sidewalls, rides better over chunky stuff. Heaviest surron around, though. I wonder if it will still fit inside my car=)

ERT BAC is bad news but Teznik or ebikezilla BAC might be better. Its all incestuous as ebikezilla might be ERT stuff... I waited 9 months for Nucular but its very good. Light speed is probably ok for the battery. Might not be that far from your location, actually. There are options from...

Im working on a conversion bike and am entertaining running dual controllers. Don't these Yamaha conversions both run split phase motors? I'm skeered of sevcons for some reason:) ( i could run two smaller, cheaper, easier to live with controllers, potentially)

Hey cool but where are you getting all your aftermarket stuff? who sells a 21 inch wheel for it? I have had to DIY all the upgrades for mine as they are mostly unavailable or backlogged 6 months etc They do have a little overlap with Alta but the bantamweight aspect is different category of...

I did a Killawatt charging session while running multitool. I ran the A pack battery down first trying to empty it. Somewhere between 10 and 15% SOC, the display bars starts to blink. 10%=3.40V per cell 5%=3.35V 0%=3.34V I rode it about 2 more miles past 0% and got down to 3.24V when the bike...

I have updated firmware but I switched the inverter FW to an older version as per Oded comments trying to get rid of regen effects. I still don't like the regen so I'll switch back and see if the temperature bottleneck goes away. I really don't care about the cold issue given how I used the...

Here is my data from todays research project. I started with a bike at 0 degrees celsius and rode it in 1/2 mile increments to see if it warms up as you ride. It did gradually. It was restricted to 9500 watts! at 0 degrees and it took 2 1/2 miles of riding to get the battery up to 11 degrees...
