## Questions & Answers

**Q: is this meant to "hang" the bike from a traditional bike rack? my Lectric is 64lbs.**
A: I would say NO.  It's meant to be a bar that the hook on your bike rack descends over and pulls down on to secure the bike in place.  My experience in that mode has been good.

**Q: Will it work on a Cyrusher Kommoda?**
A: The handle bars how big is the width of the bar that goes in the bike. If it is over 2 1/4 inches will not work.  It will attach under the seat post most seat posts are the same width. What is the distance from the seat post to the handle bar post. If it is over 29 and 1/2 inches this will not work. Lastly what is the weight of the bike if the bike is over 70 pounds this will not work.

**Q: Will it work with Yakima bike rack?**
A: Thank you very much for contacting Hyperax.

For Hyperax Step-thru adapter, its max loading capacity is 70 lbs per e-bike/bike. It works well with other major brands e bike platform hitch rack. 

Feel free to ask if you have any questions.

Thank you.

Sincerely,
Stella

**Q: Can this be used with e bike with 20" tires where the seat sits low and handlebar stream much taller**
A: Yes this works with 20 inch step thru bike

### ⭐⭐⭐⭐⭐ Super sturdy adapter for e-bikes
*by T***O on December 29, 2023*

After looking through dozens of other wimpy adapters, I was very happy to find this one - a rare design that is engineered to hold e-bikes that are heavier than conventional bikes. I figured that I'd rather invest a little more in a truly sturdy adapter, than see my expensive e-bikes fall off the car and get mangled.
