Reddit reviews Crane Bike Bell E-Ne Bicycle Bell, Made in Japan for Road Bikes or Mountain Bikes, Fits All Handle Bar Sizes & Types

I have never ridden any of the bikes you listed, but I'll chime in with a few thoughts:

• I ride a bike with a chain, and I also have a single speed with a belt (a Trek District). The Trek is my workhorse and daily go-to. In my numerous years owning it, aside from the occasional inner tube replacement and new brakes, it has received zero maintenance (literally). Belts don't need lube, they just work perfectly every single time. I'd advocate for that (but it shouldn't be a deal breaker if something else has many pro's).
  
• If you are so inclined, look at a single-speed. 450 feet isn't a huge incline, and the benefit of a single speed is nearly zero maintenance. If you have no gears, no gears will break! Trek has some good options in that arena (though they seem to be moving away from that scene, used ones are out there, as well as some new ones, like this one if you're on the smaller side). Single speed, belt drive, and disk breaks... a commuter's dream bike for a relatively flat commute.
  
• Mud/rain guards will be critical if you're going to commute in crap weather sometimes.
  
• Disc brakes are nice and will definitely out-perform rim brakes, especially when wet, but they aren't must-haves as modern rim brakes and good pads also perform very well.
  
• You will probably never be in the drops during your commute. Drops are great on a road bike and even for 'urban fun' if you have brakes accessible in the drops.
  
• Get a killer bell!! Spurcycle makes probably the loudest non-electronic bell I've ever heard. It's very pricey though, but there are some knockoffs out there that are nearly as loud.
  
• Make sure you've got good tires. If you're finding the stock tires on your bike aren't giving you the bite you want during all weather conditions your commute can throw at you, replace them! Don't get tires with no treads (like Thickslicks, which are great but ONLY for dry weather); look at reviews and make an informed choice. They may be pricey, but good tires make a difference! I'm currently eyeing some Continental tires for my Trek single speed.
  
• Invest in super bright lights that are rechargeable. People should see you from afar, and you want to see the ground in front of you when it's not too light out. There are some great LED lights out there to fit the bill, just look at reviews.
  
  And about those bikes..
  
  
• The Surly does not seem to give a great bang for the buck. Seems overpriced for the components you're getting. Anyone with more experience should veto my thoughts on this one... but I'd eliminate that from the list.
  
• Re: the two Marins, with the Nicasio you pay for creature comforts and practicality (mud gards, those massive cushy tires). With the Presidio, you pay for an absolute gorgeous bike that may need a little more money put in to have the same amenities as the Nicasio (like those mud guards? I'm not sure it comes with those). But both have internal hub, disk brakes, and both can probably accomodate any upgrades a commuter could want.
  
• That Onyx is a nice bike, but don't be carried away by the creature-comforts it offers like the integrated lights. They may be convenient, but I would want someone to speaks to their brightness before being sold on something like that. Integrated dull lights < strap-on bright lights. Other than that, it's on par with the other bikes relative to features.
  
  The last three are all great bikes, but my pick would be the Presidio, if I had to pick a geared commuter bike.
  
  All that said... you really should ride a bike before buying. Bikes have different geometry and a different feel when they ride- you may hate what others love.
  
  Good luck!

I will definitely attempt do so, thanks! I was trying to keep it on the 31.8mm portion of the bars since it gets smaller as it goes outward. I'm sure this bell will be able to conform to the irregular size.
