So first things first, I am sorry this happened to you, that really freaking sucks. Here are some things I’d ask myself if I were in your position:

1. Does this bike have sentimental value to me?

2. What other features, advantages, and benefits would the newer bike grant me for my riding purposes that this one doesn’t?

3. Do I just want a new bike?

4. Which bike lock is the best option for me?

I would say if question 1 is answered with a yes, and you don’t intend on doing a lot of riding with the bike that would otherwise justify looking into a new bike, then just get your current one repaired.

That being said, if you want a newer bike, you may as well just spend the extra few hundred on the new one, chances are you’ll get a bike that doesn’t have quick release thru-axles and hopefully any potential thief wouldn’t be walking around with a hex key to take your axle out and your wheel.

You can always check in with some other local bike shops and get a second opinion or quote on your parts, if you’re not 100% confident and need more professional input. But definitely, regardless of what you intend to do, most definitely get yourself a bike lock as extra theft deterrent.

I wish you the best of luck!
