Cruise With Comfort.

Cruisers are the most comfortable electric bicycles thanks to the laid-back frame, sit-up straight riding position, and relaxed shoulder-level arm height. You'll feel right at home on The Stunner.

It Packs A Punch, Too.

Comfort isn't the only thing The Stunner has going for it! With a 750W mid-motor, its got more zip than most eBikes. It also has an incredible range of more than 60 km (37+ miles) on a single charge.

**Please note that information regarding the expected range on a single stock battery charge on one of our e-bikes is an estimate, not a guarantee. There are many factors that contribute to the actual, real-world range for an e-bike battery such as the age of the battery, temperature, level of assist, speed, payload, and terrain. Depending on these various conditions, it is possible to get less than the expected minimum range or greater than the expected maximum range.

Bike okay - pre-assembly not so much

The bikes arrived (Stunner series) on time and with no issue. Until I went to assemble the remaining parts of the bike. The ST6 went fine. No problem.

But the SO6 was a different matter. It started out with the pedals. It appears they must have been dropped on a concrete floor as the threads were damaged. I was able, since I have a full metal shop, to fix the threads by re tapping them.

I went over the entire bike for loose bolts etc and all seemed fine. I did not check the bolt for the stand as the bike was leaning on it. Then, yesterday (June 28) I noticed the stand appeared loose. I had not noticed before as I will put the stand up and put it down. So of course there was movement. But this was not the case.

Whomever, at Biktrix, who put it together had cross threaded it in. When I finally (after much effort) was able to get the bolt out there was metal debris from the cross threading on the bolt and on the threads on the stand portion. I had to clean both of them off, then carefully re-thread both the bolt and the threads on the stand. Now the bolt could be manually threaded into the stand. Re-assembly was fine. But this should not have happened. Whomever put it together could not have missed the fact it was very very hard to turn when tightening and was loose after installation.

The bikes work fine. Are fun to ride and now function as expected. But I did go fully over both bikes again checking every single last nut and both for cross threading, improper installation etc.

I was able to put the bike together with no major issues. My wife and I went right out on a ride and had the best time. We are in our late 50's and feeling like teen agers again lol :)

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.
