Quite strong e-bicycle! The only real downside is that the throttle isn’t as “snappy” as the Surron X one example is. The throttle is pretty gradual, once you get to like 12mph it's possible. Also, I have a question a couple of unfastened o-ring on one of many fork legs. https://bamboo-directory.com/listings322687/a-simple-key-for-surron-usa-unveiled
