Know your build. Understand your ride. BAK E-MOTO helps electric dirt bike riders understand their setup, work through riding problems, and make more informed tuning decisions. Describe what your bike is doing in your own words. Ask about suspension feel, throttle delivery, controller settings, or how your components work together. BAK uses your active Garage build to give your conversation context. TALK THROUGH YOUR TUNE Explain what you feel and what you want to improve. Explore possible causes, understand how adjustments affect the bike, and work toward a useful next step. GUIDANCE FOR YOUR BUILD Save your bike, suspension, controller, battery, motor, and riding details in Garage. Keep your setup together and ask BAK about the build you actually ride. CONTROLLER AND POWERTRAIN HELP Understand controller settings, power delivery, and the relationship between your battery, controller, and motor. Ask about supported controls and where to find them. TRACKSIDE OR WORKSHOP Choose the conversation style that fits the moment, whether you need focused trackside guidance or a more detailed workshop discussion. KEEP YOUR TUNING HISTORY Save reference notes and revisit session recaps so useful information stays with you. CONNECT WITH OTHER RIDERS Share builds, ride clips, and setup conversations. Discover events and stay connected through rider profiles and messages. Built for the e-moto community, from everyday riders to dedicated builders. BAK provides AI-assisted guidance, not a live measurement or inspection of your bike. Verify component specifications and settings before making changes. Available guidance depends on your saved setup and supported component information. Some features require an account or subscription.
