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.

So far so good

Due to the weather I have not been able to ride much, or to form an opinion, or to look for any other issues.
Some minor issues with setup but nothing insurmountable.

Purchased a Juggernaut Ultra Pro - Great Bike with a couple niggles

Love the bike. Just went on a 15 mile ride. 7.5 steep down and then back up. Finished in less than an hour. Going up, was in PAS 3 and middle gear and she pulled like a champ. Came home and only at 90%. So, IMHO, great range. And the 1,000w motor is a monster - more than enough power for even the steepest hills. The two things I would change: 1. Offer a backlit LCD screen. The color screen is very nice, but disappears with polarized sunglasses. 2. Offer a dropper post. The bike is not light, but very manageable until you get into the single track. Going downhill without lowering the seat puts you in a very unstable position. I will be adding a dropper post ASAP. Other than that, love this bike. If my kids want to go out with me, I will buy others for them.
