Re: BRD RedShift electric motorcycles

The bottoms and the sides of all the 18650's are used as a surface for cooling the cells. The pack is set up to provide high volts (355V-ish), and low amps from each cell, so they can get the max amp-hours of run time possible. As a result the pack runs fairly cool anyways. Apparently, keeping the ...

Battery storage locker?

I have a baker's warming cabinet in my shop and am thinking that it would make a great place to store my batteries. Its aluminum clad and insulated and has a heating element. I'm not sure how hot it likes to run on its own yet. My shop isnt heated and we do get occasional dips in temp towards 0 F. I...

Re: Alta Motors Redshift

Gorgeous scenery and bike.

I'm interested to see how people will start to modify these as far as reverse-engineering the OEM control and battery system. Build an extra battery, for example.

So this rides like a normal gas offroad bike and the Lightbee was more like an xr80?

Re: Sur-Ron - New Mid drive Bike

Hi offroader, I'd like to buy your twist throttle even though you have me thinking more about a thumb throttle lately. I do remember my thumb tip getting very cold when riding with one in the winter.

Re: BRD RedShift electric motorcycles

I think ALta is still in limbo. No positive developments at all.

As we are talking about corporate Alta here, I'd like to see Rix's thread opened back up so he can tell us more about life with his Alta.

Re: KDX 20.0 cells trailbike conversion

Its possible that the centrifugal clutch would be effective. An ideal solution for me would be a speedway bike clutch but they are very expensive and maybe overkill for a 30 hp machine.

Re: KDX 20.0 cells trailbike conversion

I will try and do some tuning on my zeros but only one has a programmable Alltrax. I'll see If i can tune the Main Bike Board on the other. Scenario 1 : rider stalled on a very steep incline. The bikes are unable to move because the load will overload the system. Either the Alltrax or the MBB preven...

Re: KDX 20.0 cells trailbike conversion

My project hasn't seen any progress because I bought a pair of Zero X bikes which are very similar to the path I was heading down with the KDX. This has made me rethink how I want to proceed as I don't nee a third bike with the same weaknesses found in the Zeros. The Zeros are great for just tooling...

Re: Alta Motors Redshift

In theory, it shouldn't matter what map its in for highway droning battery consumption, right? I read elsewhere that an extra battery is $2500. If true, that might be a good deal.

Are any of the components off the shelf items ie what sort of throttle system is present?

Re: ME0810 doesnt run but continuous clicking heard

well the bike is working without fail for two days now. The old controller now fails the bench test so I feel better about things but still can't explain the initial problem with the new controller, maybe the Zero firmware has a learning function or something.

Re: ME0810 doesnt run but continuous clicking heard

It's quite possible there is a harness gremlin but it still defies repeatability. The new controller is definitely a change as it always give me a normal startup sequence LED. I did notice that it did not give me a yellow full throttle LED signal when i tried both throttles on it yesterday. I'm stil...

Re: ME0810 doesnt run but continuous clicking heard

I called Alltrax and the only question they asked was about the LED and voltage at pin 1. Since my voltmeter was seeing pack voltage, the tech condemned the controller. A generous member here sent me another alltrax to try. It is a bigger model AXE4855 vs NPX4834. I got it hooked up and blipped the ...

Alltrax contoller and other zero x stuff, too

Hi I'm in need of a new/used controller ie SR, AXE, NPX series. Any leads appreciated.

Also other things like sidestand brackets, inoperative batteries, dc/dc, any sort of spares, really. :)

Re: ME0810 doesnt run but continuous clicking heard

When the bike acts normally, the second faint click I hear after the big snap from the contactor closing may indeed not originate from the controller. Listening to the good bike when the key is turned on, the contactor snaps and then a moment later there is a click from the right side of the motor c...

Re: ME0810 doesnt run but continuous clicking heard

I swapped the MBB from the working bike into this one and still the same issue is present. The throttle from the good bike did not fix it either. Both throttles seem to work on the good bike. I get pack voltage at pin 1 while the problem is occurring. The alltrax passed the diode bench test they des...

Re: ME0810 doesnt run but continuous clicking heard

Today the bike was clicking until it quit as I was tapping on the controller. I rode it a short distance when it cut out and stopped. (Clicking returned) I have pack voltage at pin 1 even when its clicking at me so I think that rules out the contactor and the kill switch. Remover the controller from...

Re: ME0810 doesnt run but continuous clicking heard

It does have a contactor that obviously clicks every time you turn the key. There is a second faint click coming from the controller as the LED turns green at startup. (when throttle and bike work normally) I don't hear the faint click or see the green LED when the no throttle condition occurs. Is t...

Re: ME0810 doesnt run but continuous clicking heard

So the plot thickens. The problem is back again this morning so it is some sort of intermittent issue. The battery was at two bars so I charged the battery and the bike worked briefly but now doesn't again. I put the magura throttle from an identical bike on it and the problem is the same. I switche...

Re: Sur-Ron - New Mid drive Bike

My interest in electric drives was piqued with the Light Bee introduction. As I slowly move towards a machine like this I have somehow ended up with a pair of 2011 Zero X motos. How might these compare to the lighter Sur Ron in trail ride conditions? I'm mostly satisfied with the Zeroes except for t...

Re: ME0810 doesnt run but continuous clicking heard

Problem returned and it was in the throttle like you suggested. The clicking was a slight pulse into the motor that you could feel as a tiny jerk of the drive chain every 1/4 second. I took apart the magura throttle and had to guess as to how to time the gears in there with an ohm meter. Seems to be...
