The Cyclone is a clamshell that snaps around the chain, holds a reservoir of degreaser and runs the chain through rotating brushes as you pedal backward. It turns a messy ten-minute job into a clean two-minute one and is the main reason e-bike owners who use it actually clean their chains. Fill it with citrus degreaser, clamp it on the lower chain run, backpedal thirty revolutions, rinse and dry. It works on e-bikes with the usual caveat that you keep the degreaser off rotors and do not flood the mid-drive motor area. The CM-5.3 includes a handle and a magnet to catch metal bits.

A citrus degreaser is the right strength for a bike drivetrain: strong enough to cut old lube and road grit off a chain and cassette, mild enough that it will not damage seals or paint if you rinse it. Finish Line's citrus version is the standard; use it in a chain scrubber or brush it on, let it work for a minute, rinse with water and dry. Keep it off disc rotors and pads and away from the motor housing. After degreasing, the chain is bare metal, so re-lube before riding or it will rust and squeak. It is inexpensive and a bottle lasts a long time.

The Grunge Brush is a stiff three-sided brush that wraps around the chain so you scrub three faces at once, with a second brush on the handle for cassette cogs and derailleur pulleys. It is the manual alternative to a chain scrubber and gets into places the scrubber cannot — chainring teeth, pulley wheels, the cassette. Dip it in degreaser, scrub, rinse. On a mid-drive e-bike the chainring and pulleys collect more grime than on a regular bike, so a dedicated brush earns its place. It is cheap, simple and lasts years. Do not use it on rotors.

Finish Line Dry is the default chain lube on the shelf at most shops, and for North Texas it is a sensible default: it goes on wet, sets up to a dry film that does not grab the grit blown around on our trails and roads, and it is cheap. E-bike drivetrains see more torque than regular bikes, especially with mid-drive motors, so they chew through lube faster. Expect to reapply every 100 miles or so, more in rain. Wipe the chain before and after applying; the extra lube on the outside only attracts dirt. It is not the longest-lasting lube, but it is forgiving and easy.
