After putting about 1500 km on my V12 HT I can still say that I love it! This is the first EUC I got and still the only one I own, but it has certainly been able to keep up with my demands. It will easily get me anywhere in Saskatoon and back on one charge, and can often go several days without needing to be plugged in. When the weather permits it I use it to commute to school nearly every day. It does a great job of switching between commuting and adventuring, the ride is very pleasant on smooth pavement and I doubt I've managed to use its full capabilities on dirt trails yet.
Pros:
Nicely compact. It will fit in any car's trunk and can often be squeezed into the back seat.
Good headlight. Not much to say, it gets the job done.
Good price to performance ratio. I got mine on sale, which made it a steal.
Nice tire. The smooth strip in the middle of the tire gives a very nice ride, while the knobby sides allow it to take technical dirt trails.
Comfortable trolley handle. I'm 6,2 and the handle sits at just the right height for walking with it.
Lighting. The customizable light strips look good and help with visibility.
Bluetooth speakers. I like playing Nascar audio through them.
Nimble. This thing is small enough to fit just about anywhere, and it has lots of power to zip through openings.
Touchscreen. It's very handy being able to see at a glance how fast I'm going. And to be able to change settings without using my phone.
Adjustable pedal height. I started with them at their lowest position in order to learn. Now I have the pedals in the middle position, which gives me a good balance between clearance and stability.
Cons:
Due to how the speakers are placed, I find I have to turn them obnoxiously loud in order to hear them very well.
It also kicks other bluetooth devices off my phone, so I have to unpair it when not using the speakers.
The fact that you have to install an app in order to set up the unicycle kinda stinks. I didn't find the app particularly good ether. But I have not used it in quite a while, so that may have changed.
Its a pain trying to make any custom lighting patterns or animations for it. See previous comment about the app.
High pedals. Even at their lowest position, my cousin who rides a lot more than me said they are higher than he'd like.
Plastic shell. I've taken it through several hard face-to-pavement experiences, and the frontal piece of the shell has several cracks and a few chunks knocked out. Still works great though.
Overall, I love this machine. Most of the issues I've had with the V12 HT have been superficial and not significantly impacted the overall experience. 9.5/10 would absolutely recommend to anyone looking to buy one.
I personally will be looking for something with suspension and a metal roll cage if I ever buy another EUC, but I do not regret getting a V12 for a second!
P.S. Eevee's support is fantastic!
