If it was not obvious by now, I do have a bit of an Electric Vehicle addiction, not so much when it comes to cars, but more so with vehicles for having fun on and just ripping around on. Not the daily driver stuff. Currently I have my Kingsong S22 EUC which is probably one of my favorite Personal Electric Vehicles (PEV's). I also have a Frey Electric Mountain Bike I upgraded the motor on to a 1000 watt Bafang M620 motor. One of my more resent purchases is my SLY-08 Electric Mountainboard which again I couldn't resist upgrading with a FlipSky Controller and higher voltage and capacity battery. That thing rips now! I also have an Electric Scooter I purchased from Eevee's called the Cypress. My Electric Scooter may be the only PEV I haven't modified or upgraded so far?
I have also owned a Onewheel Pus which I did end up selling, even though I really enjoyed riding it. I just found it to be the most unpredictable PEV I owned in terms of safety, as at any moment it can cut out if you push it a bit too hard, and that can be as easy as going at a moderate speed from concrete onto grass, and then the next thing you know, you are sprawled out on the ground... Of course I upgraded and modded that one too :)
I have always wanted an Electric Motorcycle, but they can be kind of expensive for something newer and with decent specs. A lot of the cost, like with a car is in the batteries. And more range means bigger batteries which also means added cost. I found a used 2011 Zero XU that had recently had it's battery replaced with a nice large and powerful custom built (for this bike) 72 volt 100ah Battery capable of 400 amp output. The price of the battery is probably about $4000, which is $1000 more than I paid for the bike. But keep in mind the current version of this similar styled Zero Electric Motorcycle is around $16,000 before tax and PDI and all the other stupid add on charges... So closer to $20,000!!! I will be into my 2011 Zero XU for around $4500 all said and done and it will actually be somewhat comparable to the newer model in terms of power and range, for sure range.

when I bought the Zero XU I was aware that it had a couple issue, the main one being the throttle not engaging 100% of the time. Sometimes you need to roll it on a second time to get the bike rolling, once rolling it seemed fine. I am pretty sure it was the controller which meant replacing the controller. I don't want to drag this on too long so getting to the point, I ended up deciding to instead of trouble shooting the multiple problems mostly to do with wiring, I would simple replace all the electronics other than the battery with a complete Brushless Motor, Controller and full Harness and Display Kit. That might seem like an expensive choice but this kit will essentially make all the guts of my bike new and it will be a major upgrade in terms of speed and even range as Brushless Motors allow for battery regeneration and are a lot more efficient than brushed motors in general.
My wife already rides my electric Mountain Bike a lot and the plan is she will be able to scoot around on the Zero XU. We can also go out on rides together, as I have my 1993 Ducatti 750ss so that will be a lot of fun! I just need to wait on the parts to arrive now and put it all back together. I hope to document at least some of this upgrade and conversion so join me if something like this is interesting to you :)
