E-bikes like the Key West 2.0 often prioritize comfort and agility, but AIMA’s model is among the most successful in these areas. Its relaxed geometry, adjustable fit, included suspension seatpost, and balanced weight help it to be nimble and enjoyable to ride.
AIMA offers the bike in two sizes: a Regular that fits riders from 4’11” to 5’10”, and a Large that accommodates those between 5’4″ and 6’1″. We tested the smaller model, and despite being outside the recommended height range (I’m 5’11”), I found the ride comfortable and ergonomic.
The bike offers a fair amount of adaptability, with a seatpost that has around 6″ of adjustment in saddle height and an adjustable stem that alters handlebar height and reach.
Since our test bike was a bit on the small side, I set the stem to roughly 45 degrees and set the saddle somewhat lower than I typically would to keep the riding position comfortable. I was relieved that the motor offset the difference in leg extension by giving me enough power to prevent any strain.
The wide, swept-back handlebars, ergonomic rubber grips, and supportive spring saddle felt great, keeping me in a comfortable and relaxed upright position. I found myself easily slipping into the cruiser mindset, pedaling at a casual pace so I could enjoy my surroundings and the ride experience.
Thanks to the suspension seatpost and 27.5″ wheels, rolling over bumps felt smooth—more like gliding or floating than anything else. Steering was relaxed but also responsive, so the bike was easy to control without feeling sharp or aggressive. Accelerating was fast and efficient, feeling well-suited for both commuting and cruising.
Speaking of those two uses, the Key West 2.0 is decidedly a cruiser first, but it still has plenty of commuter DNA. In addition to its place in the mid-weight category, it’s well-equipped for functionality. The bike includes integrated lights, fenders, turn signals, and a high-capacity MIK-HD cargo rack, so it’s set up for utility in addition to daily transport.
As I’ve mentioned previously, I was impressed by how seamlessly and quickly the motor engaged; it felt intuitive and dialed-in.
The Key West’s level of customization was appreciated, though I do have one area of critique. Adjustments to the bike’s Class setting must be made by authorized technicians at AIMA dealers, which means that riders who make a change but want to return to previous settings will need to go through the ordeal of going back to the bike shop. This may present an inconvenience to those who live far from a dealer location.
Otherwise, I appreciated that many changes can be made from the display’s settings menu, including switching between torque and cadence modes.
Additionally, the Bafang Go app is worth a mention. In addition to also offering motor tuning and serving as a hub for important ride data, it also can be used to track rides or get turn-by-turn navigation to specific destinations.
Overall, the experience of riding, using, and customizing the Key West 2.0 was great, and I’m impressed with how much the bike offers at its price point between $1,500 and $2,000.
