I purchased an UBCO 2x2 2.1kw bike exactly one year ago. So far, I have been very happy with it overall. My use is mainly utility/recreational around our property. It is far quicker to hop the UBCO on and go check a fence or help the neighbors with an escapee horse than our SXS or jeep, and at no cost for fuel/oil/filters as we have solar to charge it. The near-zero need for maintenance compared to a 2/4 stroke gas bike is a massive time saver as well.--It's one less thing to keep up with on the farm with other constant projects. The performance is pretty decent as well. A friend of mine has as Surron e-bike that is pretty quick, but the utility of the UBCO with it's cargo racks and added panier frames makes it the clear choice for WORK. I can easilly carry a chainsaw, fuel, other tools and a rifle to pop out for trail maintenance on the back 40 and navigate tighter areas that the SXS would be too wide for. The 2WD really shows its value in this respect, and it has the ability to haul more weight than most other e-bikes in it's price range. In eco mode, the Surron beats it in speed; but this is a work bike primarilly. Cutting down the trails for recreation is a blast and having storage on board for water, first aid, parts, etc. is a big benefit. All this being said, a BIG seling point for me was the UBCO servcie. Their team was VERY communicative, and assisted me in the purchase process. They were also considerate enough to work with me on pricing/promos for service members (this was purchased as post-mobilization present for myself, and I love it). Deliver, packaging, assembly and ease of use getting it going were all flawless. The ONLY complaints I could potentially note with the UBCO are that you seem to have to have the app on your phone to turn ON the headlight. I also get an overcurrent fault on the rear moter when the 2.1kWh battery is over 90% charge; and this fault shuts off the rear motor. Turning the bike off/on clears it; and this only happens about every other time I charge it fully then take it out on a run. If you can spring for the larger battery over the 2.1kWh model, DO IT. We have a lot of rough trail, hills and some mud on our property and it tends to drain the battery quickly. I wish I had gone with the larger battery for more run time; but having to return to the shop on 3% power to charge it up after a day of work or a couple continuous hours riding trails is not the worst thing. Overall, I'd give the bike a solid 8.5/10 due to the headlight oddity, fairly regular overcurrent fault, and it's overall performance. UBCO would get a 10/10
