The MSR PocketRocket 2 is a canister stove that runs on isobutane-propane fuel canisters, which are sold separately.
It weighs 2.6 ounces and folds down to 3.1 by 1.7 by 1.3 inches. It boils one liter of water in about 3.5 minutes, and the flame adjusts from a full boil down to a simmer.
E-bike compatibility: the folded stove fits inside most cook pots, so it adds essentially no packed volume to panniers or a trailer.
