Stunner Step-Thru 6 Review

The Biktrix team has been awesome, I love my bike and would highly recommend. I am really glad I chose your company especially after a bad experience prior with a local brand that doesn't even compare.

Customer service and the bike SUCK

The ebike front fork fell off right out of the box. The bike is broke and is unrideable. Front fork pulls apart and wobbles making it unrideable. Customer service is offering a 40% for a new front fork on a bike that was sent already broken before I recieved it. I would like to sent the bike back for a full refund.

Love our new bikes

Solid construction bike with plenty of power

I went deep down the rabbit hole researching every electric bike under the sun. After countless reviews I found one that was comparing bikes going up hills. To my surprise not very many were able to do this easily. That's when I started realizing the benefits of a mid-drive versus a hub Drive. Although there was some fear around it wearing down the gear shifters. So when I found this bike had an internal mechanism that was less prone to needing tune-ups I found it quite the happy medium. Plus I am 6 ft 2 so looking for a decent size bike I could set up straight on. Ordering a bike online without writing it is quite scary to say the least. When I got in the mail it was quite easy to put together. The ride is quite Pleasant, I am able to set up right, and feel confident the bike will hold up together. As a comparison I got my wife a $1,000 bike off of Amazon to save a little bit of money. The comparison of this bike and that is not even in the same ballpark. Well worth the extra money to get a high quality bike. Oh also make sure you get the shock absorber seat it is well worth the money.

Stunner 6 step thru purchase

I am very pleased with my 2 stunner 6 step through bikes.They are great bikes. However, I must tell you the "stock" seats that came with the bikes are awful. They are very uncomfortable. Maybe the most uncomfortable seats I have ever sat on. They are a disservice to the bike. However, I do commend your companies response when I reported this issue. Your company is forwarding 2 replacement seats. I have not yet received them, but they have to be an improvement over the stock seats. The only other issue I have encountered, is the inability to register the warranty on one of my 2 bikes. I received a warranty certificate on one bike, but despite my effort to register the 2nd bike, I have not received the certificate on the 2nd bike. Im not sure what is going on there.

order confirmed 2/7 . still no bike 3/8. review leaning towards negative

Great E/bike

The bike rides and operates as it should. Fast shipping great packaging. Excellent service when I called to ask questions. Great company to do business with. If you’re looking for an E bike contact Biktrix.

Well made bike

The shipping was on time packaging was excellent.
I talked to Mathew in service and parts in which he had excellent knowledge, and I had the information I needed promptly.
This is the bike that I have been wanting mid drive 750 W good amp hour battery, internal rear hub gearing.
What’s not to like about the bike ( nothing ) .
Great bike.
