Gears run from Gear 1 to Gear 24 on a magnetic brake, with Gear 88 held back as the emergency brake. The handlebar computer reads out RPM, watts, kilocalories, trip distance, elapsed time and the gear in use. Nothing pairs to this bike. It leaves out Bluetooth, apps, heart rate tracking and accounts. It stands 44 in. tall, 26 in. wide and 51 in. deep at 87 lb assembled. The frame is rated for a rider up to 350 lb under EN\/ISO 20957-1 Class S.\u003c\/p\u003e\n\u003cp\u003eResistance is magnetic and the gear number is the only figure you set on an M3. The bike runs a fixed gear system with no freewheel, so the cranks keep turning for as long as the wheel turns and a rider slows the bike through the pedals rather than coasting to a stop. The M Series pedal set takes either a clip-in cycling shoe or an ordinary training shoe held by the pedal cage strap, so two riders in a household do not need the same footwear to share one bike.\u003c\/p\u003e\n\u003cp\u003eRider height on the M3 runs from 58 in. to 84 in. and the maximum user weight is 350 lb. The computer runs on two AA alkaline batteries, which is the only power the bike ever asks for, and the frame carries the EN\/ISO 20957-1 Class S classification for controlled environments under trainer supervision. Warranty on Keiser M Series Cardio runs three years all inclusive, excluding labor and wearable parts, with ninety days on the wearable parts: handles, pedal cage, straps and saddle. Three Keiser parts fit an M3 and each one is its own order: a \u003ca href=\"\/products\/keiser-gel-seat-cover\"\u003eKeiser Gel Seat Cover\u003c\/a\u003e over the \"narrow\" saddle, a \u003ca href=\"\/products\/keiser-floor-mat\"\u003eKeiser Floor Mat\u003c\/a\u003e under the frame and a \u003ca href=\"\/products\/keiser-m-series-assembly-maintenance-kit\"\u003eKeiser M Series Assembly and Maintenance Kit\u003c\/a\u003e for the bolts that want a torque figure.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"overview__image\"\u003e\n\u003cimg alt=\"Keiser M3 Indoor Bike with the computer display above the handlebar\" decoding=\"async\" loading=\"lazy\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0044\/9341\/0393\/products\/M3_5501_RGB_Reflect-cinv-1584484576267959.png?v=1764194021\"\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spec-banner\"\u003e\n\u003cdiv class=\"spec-card\"\u003e\n\u003cp class=\"spec-card__label\"\u003eResistance\u003c\/p\u003e\n\u003cp class=\"spec-card__value\"\u003eGears 1 to 24\u003c\/p\u003e\n\u003cp class=\"spec-card__sub\"\u003eMagnetic, with Gear 88 as the emergency brake\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spec-card\"\u003e\n\u003cp class=\"spec-card__label\"\u003eConnectivity\u003c\/p\u003e\n\u003cp class=\"spec-card__value\"\u003eNone\u003c\/p\u003e\n\u003cp class=\"spec-card__sub\"\u003eNo Bluetooth, no app, no heart rate tracking\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spec-card\"\u003e\n\u003cp class=\"spec-card__label\"\u003eFootprint\u003c\/p\u003e\n\u003cp class=\"spec-card__value\"\u003e44 x 26 x 51 in.\u003c\/p\u003e\n\u003cp class=\"spec-card__sub\"\u003e87 lb assembled\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"spec-card\"\u003e\n\u003cp class=\"spec-card__label\"\u003eMaximum user weight\u003c\/p\u003e\n\u003cp class=\"spec-card__value\"\u003e350 lb\u003c\/p\u003e\n\u003cp class=\"spec-card__sub\"\u003eRider height 58 in. to 84 in.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"value-bar\"\u003e\n\u003cp class=\"value-bar__item\"\u003eMagnetic resistance, gears 1 to 24\u003c\/p\u003e\n\u003cp class=\"value-bar__item\"\u003eFixed gear drive with no freewheel\u003c\/p\u003e\n\u003cp class=\"value-bar__item\"\u003eTwo AA batteries and nothing else\u003c\/p\u003e\n\u003cp class=\"value-bar__item\"\u003eEN\/ISO 20957-1 Class S\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003csection class=\"section--dark\"\u003e\n\u003cdiv class=\"container\"\u003e\n\u003cp class=\"section__eyebrow\"\u003eThe ride\u003c\/p\u003e\n\u003ch2 class=\"section__title\"\u003eHow it works\u003c\/h2\u003e\n\u003cp class=\"section__lead\"\u003eEvery control on the M3 is mechanical apart from the computer, and the computer keeps its readings on the bike.

Those six figures are the whole readout, they update as you ride, and they go nowhere afterwards. Power on the screen lets you compare gear changes between one session and the next, because a gear number on its own says nothing about how hard a rider is working at that cadence. The computer runs from two AA alkaline batteries seated behind the screen, so there is no cable to run to the bike and no outlet to find in the room.\u003c\/p\u003e\n\u003cp class=\"tech-card__stat\"\u003eSix figures on one screen\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"tech-card\"\u003e\n\u003ch3 class=\"tech-card__title\"\u003eGears 1 to 24 on a Magnetic Brake\u003c\/h3\u003e\n\u003cp class=\"tech-card__text\"\u003eResistance on the M3 comes from magnets instead of a friction pad, and the gear lever moves them to change the load.

The machine itself is 44 in. tall, 26 in. wide and 51 in. deep at 87 lb, and the 26 in. across the handlebar is the width that has to pass every doorway between the front step and the room it lives in.
