A rubbing disc brake is the most common e-bike annoyance, and a slightly bent rotor is the usual cause after the bike has been leaned on a rack or dropped. The DT-2 is a slotted steel fork that grips the rotor so you can bend it back a hair at a time while spinning the wheel and sighting through the caliper. It is a simple tool that replaces the adjustable wrench people use and regret. Clean hands and a clean tool matter — any oil transferred to the rotor will contaminate the pads. Heavy e-bike rotors are thicker than road rotors and take a bit more force.

When you change hydraulic brake pads you have to push the caliper pistons back into their bores, and doing it with a screwdriver scratches pistons and cocks them sideways. The PP-1.2 is a flat, wide press that pushes both pistons back evenly and is thin enough to fit into the caliper with the pads removed. It also works to spread pads that have crept inward after a lever was squeezed without a rotor. Many e-bikes ship with Tektro or Shimano hydraulic calipers, and this tool fits them. Clean the pistons before pushing them back so grit does not get forced past the seals.

EZmtb's bleed kit is the widely sold generic kit with syringes, tubing, a bleed cup, a selection of fittings and, in most versions, a bottle of mineral oil. It covers the mineral-oil brakes that ship on most e-bikes — Tektro, Shimano and Magura — and the fittings list usually includes SRAM adapters too, but verify the exact kit contents against your brake model before buying. Bleeding is a methodical job, and a spongy lever on a heavy e-bike is a safety issue, so follow the brake maker's procedure. If you are unsure, this is a job to hand to a shop or get an E-Bike Assessment before riding with questionable brakes.
Best for: Mineral-oil brake bleeds at home · Tektro and Shimano brakes on e-bikes · Riders comfortable following a detailed procedure

The TW-5.2 covers the torque range that matters for most e-bike cockpit and brake work: 2 to 14 Nm, which includes stem bolts, brake lever clamps, rotor bolts and rack bolts. It is a 3/8-inch drive click wrench with a ratcheting head and a clear scale. Over-tightening stems and display clamps on aluminum or carbon bars is a common home-mechanic mistake; a click wrench removes the guessing. Pair it with a set of hex and Torx bits. It does not reach the higher torques needed for crank bolts, cassette lockrings or axle nuts, which need a wrench that goes to 40 Nm and beyond.
Best for: Stem, bar and brake lever work · Rotor bolts · Rack and accessory bolts
