I don't know for certain, because I bought the tubes for a knee scooter which is probably lighter than an electric scooter. However, it would seem to me that it would also work for your situation. I hope my answer is at least somewhat helpful. **Q: Does this work for both wheels on a Carryme folding bike? And does it take 80 lbs. of pressure?** A: Yes **Q: Can 16x1.5 tire be replaced with 16x1.75?** A: In most cases yes. The tire is just a little bit wider. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/117684677-8x1-1-4-200x45-inner-tubes-with-angled-valve-stem](https://www.desertcart.us/products/117684677-8x1-1-4-200x45-inner-tubes-with-angled-valve-stem) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-29*
