## Questions & Answers

**Q: Any idea if this would work for a livestrong (ls5.ou) stationary upright bike)?**
A: Honestly, thanks for the info, and looking at the exercise bike, you might need to check the length of the other arm crank, and see if it is a diamond hole or a square hole by setting the remaining arm crank on its down position. If it’s a diamond hole, then here it is. There are similar answers, as I looked up a YouTube video on how to disassemble one, and there was a diamond hole featured for one second. So if this answers your question, then I’m glad to help.

**Q: Does this work on the bafang e-bike?**
A: There are many Bafang E-Bikes, you need to see if yours has a diamond hole or squared one if you take out the bolt for your arm crank. Then you measure the size of the hole in the arm crank.

**Q: Do I need to buy a bolt separately?**
A: If your original bolt OK can use the original bolt, if not, you may need to purchase separately.
Thank you for your question.

**Q: Would this work for a Schwinn IC3?**
A: No it will not. The IC3 diamond is larger
