Your whole garage in your pocket. Save every bike, log every setting, and watch service intervals tick down as the hours and miles add up, so nothing sneaks up on you. Service Assistant is the setup and maintenance logbook for people who work on their own bikes- dirt, street, ADV, or MTB. Add a motorcycle or mountain bike, save its baseline settings, then build a record you can trust instead of trying to remember what you changed three rides ago. A SERVICE CENTER THAT COUNTS DOWN FOR YOU Set the intervals that matter to you the most- suspension service every 40 hours, tune-up every 15 hours, chain every 300 miles. After a ride, log your hours or mileage once. Service Assistant subtracts from every interval automatically and tells you what's coming due before it becomes a problem. You can track by mileage or runtime depending on the bike type. Engine, suspension, chassis, brakes, electrical, drivetrain: if it runs on a schedule, you can track it here. SETTINGS YOU CAN ACTUALLY FIND AGAIN Save a baseline for every bike, then log what you change as you dial it in. Clicker positions, sag, spring rates, tire pressure, gearing, bar and lever position. Record it, compare it, and get back to it when a setup change doesn't pan out. KEY FEATURES • Unlimited bikes — a full profile for every machine you own or maintain • Baseline settings — the known-good starting point you can always return to • Setup notes — suspension, tire pressure, ergonomics, conditions, results • Custom service intervals — by engine hours or mileage, set however you want • Automatic countdown — add hours or miles once, every interval updates • Complete service history — what you did, when you did it, on which bike • Slacker Virtual Remote — turns your phone into a large, easy-to-read display for the Slacker digital sag scale BUILT FOR RIDERS AND THE SHOPS THAT KEEP THEM RUNNING Whether it's one bike in the garage or a rack of customer machines, everything lives in one place — searchable, organized, and there the next time you need it. FROM THE MAKERS OF SLACKER Service Assistant is built by Motool, the team behind the Slacker digital sag scale — the patented suspension setup tool trusted by riders, tuners, and shops since 2014.
