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.

I was looking into replacing my old beat up mountain bike with a e bike for Christmas and found this one and it’s an amazing bike and super fun and easy to ride. This is my first e bike and probably won’t be my last, this bike is a lot of fun to ride and it’s a great overall experience

Aventon continues to impress with end of year discounts on already low e-bike prices. And my son-in-law was able to assemble the bike for me (from a to z) in 1.5 hours using the easy to read and understand directions.

alot of the reviews are very interesting to say the least, ill start off by saying, this is my first ebike, and i came into this knowing i purchased the cheapest bike they had, no shocks, so im not going to complain about the ride, small little tires so im not going to complain about any flats, and a small motor so im not going to complain about it being not powerful enough.

i will say, luckily im mechanically inclined, but i can totally see the "how to" build your Soltera video throwing people off since its for the 2 and not the 2.5 and there are some differences but with some patience and some common sense i was able to build mine and ride it in 30 mins.

as far as performance goes im not sure what people where expecting out of this model but i took it to work today (only a 3.5mi ride) but still it performed just as expected, maybe even better, took little to no effort to cruise at 19mph and when my legs got tired just apply the throttle and hold for 30 seconds then keep pedaling, actually got to work early because i avoided so much traffic and i didnt feel any sort of being tired from the ride while at work due to how easy it is to ride.

the display and app work well together, the oem lights are bright enough, the gearing is fine for a city bike, i think alot of the one star reviews are from people expecting $2,000 performance from a $1,000 bike, i dont regret my purchase at all, and if i get a flat then ill replace the tires with more rugged tires no big deal.

if Aventon is reading this i really think you should pull a 2.5 off the line and have your team assemble it on video and post it to your site, or youtube channel would kept you avoid alot of these one star reviews.
