The M19 packs the bits most riders actually need — hex keys from 2 to 8 mm, Torx T25, screwdrivers, spoke wrenches and a chain breaker — into a tool small enough for a jersey pocket or a top tube bag. The build is solid with steel bits and a flask-style case. On an e-bike, the common roadside jobs are tightening a loose stem, adjusting a rattling rack bolt, or re-seating a dropped chain, and the M19 handles them. The 8 mm hex is handy for some crank bolts and axle nuts on folding bikes. The chain breaker works but is slow; it is there for emergencies.

The Mini 20 Pro is Topeak's compact tool with a twist: it includes a tire lever and a chain hook in addition to the usual hex and Torx bits and a chain breaker. The aluminum side plates keep weight down and the bits fold out cleanly. It is slightly slimmer than the Crankbrothers M19 and includes a neoprene pouch. It is a good all-in-one for e-bike commuters who want one thing in the bag that handles a flat and a loose bolt. The tire lever is fine for commuter tires and will struggle on tight fat-tire beads, so fat-bike riders should still carry real levers.

The GP-2 is a tiny box of self-adhesive patches and a sandpaper square that fits in any saddle bag. Glueless patches are the right roadside tool: no waiting for vulcanizing cement to flash off, no dried-up tube of glue when you finally need it. Scuff the tube, press the patch hard, reinstall. They are reliable on punctures from thorns and glass; they are not for large gashes or valve-base tears. Many riders buy two or three packs and stash one on each bike. Pair it with tire levers and a pump and you have a real flat kit for a few dollars.

Pedro's levers are wide, flat, plastic levers that are very hard to break and do not chew up rims. That width is why they are the standard recommendation for fat and plus-size e-bike tires, where the bead is tight and the tube is thick. They hook onto a spoke while you work the second lever around. Two in a saddle bag weigh almost nothing. They are a little bulky for a jersey pocket and will eventually round off at the tip after many tires, at which point you buy another pair. For the money there is no reason to own anything else.
