Me and my wife just love riding our SINCHs. Mind’s is grey cloud (above frame) hers is a red (lower frame) both 4inch **** bikes but very comfortable rides thanks AVENTON FOR MAKING A GREAT PRODUCT!!!

This review is for the Soltera 3 ADV. I absolutely love this bike. It’s a bike for people who love to ride bikes. Dare I say even for bike nerds. I’ve been commuting-errands on this for two weeks. It is so damn cool. It’s light. It doesn’t look like an e-bike. It looks like a simple bike. Non-descript.

The single-speed belt drive is so frickin cool. Silent. No maintenance. Wow. The single gear ratio is a good compromise. Works for me on modest hills. Don’t need to put much effort in. On steep hills, yeah I gotta stand and pump. But so far that happens only on a consecutive block or two where I live even when climbing 800ft. It’s hilly in Berkeley, CA.

I ride it in Sport and Turbo. Depending on elevation gains I’ll get 30-40 miles. I’m not shy about using turbo on this bike.

It’s the perfect commuter bike. You can take it up/down stairs easily. Lift onto front bus racks. Even though Aventon doesn’t sell a rear rack you can mount an Old Man Mountain Divide rack on the rear. And I stealthed out the branding with black vinyl. So badass. Love, love, love this bike.

I love, love, love my Soltera 2—and that’s not something I say lightly after putting 2,500 miles on it across nearly every connected borough of New York City (sorry, Staten Island… eventually I'll reach you).

One of the biggest wins for me is that it actually looks like a regular bike. So many e-bikes are clunky and heavy, but the Soltera 2 keeps a lightweight, clean, classic **** profile. I upgraded from the original Soltera, and the jump was absolutely worth it. The ride feels more refined, more confident, and just better suited for serious city mileage. Early on, I was popping a tire almost once a week—but that turned out to be 100% user error. I ride hard, and I was under-inflating. Once I fixed that the issues disappeared. Since then, the bike has been rock solid. The build quality is no joke.

Most of my riding is on pavement, but NYC isn’t just smooth asphalt—there’s dirt, sand, water, broken paths, and surprise terrain everywhere. Upgrading to hybrid tires was a game-changer, making the bike feel even more versatile and planted.

One fun thought: if the bike didn’t have a throttle, it could qualify for some bike marathons. That said, there are 2 things I wish it had:

Cooler built-in lighting options, especially since I ride mostly at night through Central Park
A built-in alarm system and GPS tracker, which would be huge for city riders

None of those are deal-breakers, though. I'm looking forward to the future evolution of the model. Bottom line - the Soltera 2 has proven itself over thousands of real, hard city miles. It’s sleek, reliable, fast, and genuinely fun to ride. If you want an e-bike that doesn’t feel like an e-bike—and can handle NYC life without blinking—this one absolutely delivers.

This isn't your typical review, rather than first impressions this is my review after owning a Soltera7 for 3 years and putting 5,430 miles on it.
Value: The Solterra models are an excellent value for the money, for just over $1000 you get a quality e-bike that works like advertised
Battery life/Range. The range really depends on a number of factors; what level you set it on, hills, wind, etc. I typically rode on level 3 and when I was riding on flat ground my range was 50-60 miles. My wife rode on Level 2 and achieved 60-70 miles range. Of course, if you go up hills, are fighting a tough headwind, or use level 4 or 5 the range is shorter. I think the emphasis on range is a bit of a red herring anyway since an average rider doesn't typically ride more than 30 miles anyway.
Caveat: The Solterra7 has a cadence motor while the newer 2.5 has a torque motor. There are pros and cons to each and I actually own e-bikes of both types. Without getting too far in the weeds, the Torque sensor bikes feel more like a regular bike and goes faster on flat ground, however they require a lot more effort going uphill. Cadence bikes don't require much effort and are a breeze going up hill, though they eat a lot of battery when doing so. I would recommend a torque sensor bike for younger people, or people who still want to get a workout, and cadence sensor for older/recreational riders who just want to get out on a bike
Quality: I have had zero issues with the Solterra7 other than the free fender that I got with the bike broke in 3 months. I had it replaced with a higher quality fender
Display/App: The display is very functional and easy to see while riding and the app is good if you want to use it.
Gearing: No issues with the gears though I would love an extra gear to go a little faster at times
Brakes: Never had any issues with the brakes.
Ride: The ride is a little stiff, especially since there isn't a front suspension system, but I added a suspension post to the seat and that helped
Overall: Thrilled with the Solterra7, it's a great value. I haven't ridden the new 2.5 with the torque motor but it its likely a good value/product too.

Bought the bike as a Christmas present for my niece who recovering from a spinal problem. Now she can bicycle freely, and when she tires, she uses the electric feature. She is very happy. Buy at Christmas, order early.
