Review: Best Bike Lock Ever - This is the best Bike lock I have ever gotten . I purchased 2 of these , one for each of our E-Bikes . One night at a campground someone tried to steal our bikes and they could not cut through the chain. It is a heavy thick , very durable chain . I have since purchased one for our genny on our RV . The lock is covered so it won't get wet or dirty .It comes in many lengths and with multiple keys .
Review: Secure - It’s definitely worth the purchase, keeps me stress free knowing I have my bikes secure! 🙌🏼 the lock quality is awesome, weight, length and functionality great!!
