Should I Buy It?

If performance and durability at a good value are what you seek in an e-bike, the Aostirmotor S17 is worth considering.

However, consider the potential front wheel issue and battery mileage according to your needs before purchasing.


  • Great value
I've put 150 miles on the bike and it's been fantastic. The only issue I had was the front chain guide and derailer mount was bent in shipping causing it to not shift properly. I was able to bend everything straight and it shifts perfect now. I ride mostly dirt trails with hills and single track. The bike is very powerful and gets me up and down no problem. I get around 20 miles to a charge in the dirt, closer to 28 on the street. I use mostly PAS 2 and 3. I wish the throttle worked from a dead stop, maybe there's a setting for it but I can't find it. Brakes are outstanding. Overall very pleased with the bike and would recommend it for light duty trail riding or street. ... show more

  • Don't buy from Costal-EBikes
I feel that the Aostirmotor S17 is one of the best value for dollar e-bikes available. The bike's aggressive, angular design and dual suspension is far more mtn bike than city commuter or beach cruiser, it is however exactly what I was looking for and fits my use case perfectly. I am 6'2", small riders might find the stand over height a challenge and prefer a step-through style bike. The bike was easy to assemble, with the provided tool kit, no fitment problems, remember to check ALL fasteners for proper tightness. I would advise against purchasing from Costal-EBikes, they were not helpful with the return of the first Aostirmotor S17 e-bike I purchased. The bike was so badly damaged that my FedEx driver refused to deliver it to me. I returned it to Costal-EBikes, who failed to issue a refund authorization, after the bike had been in Costal-EBikes possession for five business days I contacted Amazon Customer Service who stepped in and issued a refund. ... show more

  • Good bike
Good bike feels well made was able to get 34.5 mph it’s 48v so acceleration is kinda meh but doesn’t jerk like 52v ebike… my 52v juiced ripracer accelerates a lot faster but is 6mph slower with topspeed.. going to get slick tires and maybe change the gearing to have better acceleration…the rear suspension sucks and not many options out there stock is 1500lb spring😑… front fork is good the front end floats over everything the rear end sucks … finding a good 26x3 slick tire for pavement riding is kinda hard… but 26x 3 is an amazing tire size .. the bike is long… longer than an Ariel rider keplar but man does it look a lot better in person… the long wheel base is amazing at high speed very very stable, very quiet motor… okay so the reason I gave this bike 3 stars is not really the bikes fault.. but the company..I messaged them and specifically said I want a black bike they agreed and said okay.. what did I get? The red white and blue one, the bike came with a striped star nut which was installed incorrectly and a bent derailer now I’m paying a shop to fix all these issues and also going to wrap it black which is even more money out of my pocket… I really trusted them to atleast have the color right… if they told me the color wasn’t available I would understand but they told me it’s available and they will do it… man trust plays a big role when spending almost 2k on a ebike… I really can’t recommend this bike because of the company yes communication sucks… I really wanted to like these guys but I feel like they just don’t care ... show more

  • Ebikes have really came a long ways!
The media could not be loaded. Yes, at first I was skeptical but I looked online and I seen peoples reviews on YouTube and I mean it this bike is actually a nice bike like it’s comfortable to ride it’s solid and we’re getting to the point where it’s almost like motorcycles. I thought maybe just because it was from China that may be it would be cheap but it’s not, it’s well put together and solid! ... show more

  • This is a review from someone bought the bike
First I bought this bike thinking it would be awesome with 1500 motor. It turn out it was a piece of garbage. It arrive broken on the the battery pack and didn't fit in its holder. This how the workmanship of china is. Poor to say for 2000 dollar bike this is sad. I had a hard time to turn the key to on which is cheaply made. It looks like the battery was a use one. The power switch would turn and turn off immediately and won't turn back on. I try to ask the company to replace the battery but wouldn't do it. all and all I wouldn't recommended this company and its bikes. ... show more

  • Front wheel doesn't match quality of the bike
This felt like a quality bike when I bought it and it still does except for one thing. The front wheel is a single wall aluminum rim that may be too lightweight for the bike. I ordered a double wall aluminum wheel with 12g spokes (front had 14g spokes whereas the rear wheel already has 12g spokes which are heavier). The new wheel cost $180. The original front wheel makes terrible noises that seem to originate from the spokes as well as the rim itself. The bearings don't feel smooth either. In general you feel like the front wheel could fail. The Customer Service people are nice but they can't solve the problem with the front wheel being too lightweight. ... show more

  • Slow and heavy
I was so disappointed in how slow this bike is. It is a little slower than my wife’s 500 watt ebike in a drag race. Maybe somethings wrong with mine. I like the bike otherwise. I am returning the bike. The tires measure 29 inches in diameter and 3 5/8 inches wide. All 26 inch fat bikes are this way there is nothing 26 inches about any of them. The wheel is 22 inches in diameter. ... show more
