## Questions & Answers

**Q: What are the inner dimensions of this U-lock?**
A: Hi, thanks for your question. The inner width of the U-lock is 105 mm and the inner height is 200mm. We hope this answers your question. Best regards, team Sigtuna Gear

**Q: Where do you store the cable, when it's not in use?**
A: Hi, thanks for your question. A velcro strap is provided with the U-lock to connect the cable to your bike frame. Please see how this is done on of the product pictures. Best regards, Team Sigtuna Gear

**Q: Hi, Can I use it to lock my electric scooter?**
A: Yes

**Q: My mounting bracket does not fit on my frame. What do you recommend to do?**
A: Hi, thanks for your question. May we ask, what kind of bike do you have? This can help us in providing a solution. Our mounting bracket is designed to fit 90-95% on all bikes, but sometimes there is case of smaller or wider tubing and in some cases triangular tubing as well. This causes the mounting bracket to not (completely) fit on the frame. With a smaller frame we recommend to use the rubbers that are provided with the lock to tighten the grip of the bracket to the frame. With a wider frame the solution is to use longer bolts to connect the bracket to the frame. The bolts that are used are common hex bolts and available at your local hardware store. With a triangular tubing we recommend to put the lock in a side-mount on the seat tube. The seat tube is almost always a regular tube that works fine with the bracket. Please let us know if this helps you connecting your mounting bracket. You can contact us at customers@sigtunagear.com. Best regards, Team Sigtuna Gear
