Review on Heavy Duty Seatylock Mason U Lock - Patented Diamond Secure Anti Theft Bike Lock With Keys - Ultimate Protection For City, Electric, Mountain Bikes, And Scooters by Paul Walton

The Good:-Heavy duty-Thick-Easy to use-Long U bar-Solid constructionThe Bad:-HeavyThe Bottom Line:I just tried this Seatylock and wow this thing is hefty. I’m pretty sure no one is getting through this thing. It is easy to use and has a long U bar so you can lock your bike to the post easily. It comes with a key lock so no combo to remember. The only downside is this heavy duty ness comes at the price of weight. This lock is not light. Overall, I would still recommend this Seatylock if you’re looking for a heavy duty bike lock.
