So, I recently just started to ride my bike to and from school again because the weather is getting warmer and I think I need some exercise too. Ever since my last bike got stolen at school late last year I stopped biking to school entirely till now. I bought a really good lock (Kryptonite New York Lock) and a new bike (GT Avalanche 3.0). I'm 17 and I don't have much money so I can't afford to lose another bike, school is also pretty far and taking public transit would also be expensive. My question is if I should take off my front wheel and lock it with the rear wheel through the seat stays or should I have another cable to attach to my front wheel or should the lock go through the down tube as it is the strongest part of the bike?
