BikeTalk vs FlowState VESC

"Car back!" The phrase every cyclist knows. The warning yelled down the pace line. The thing you wish you'd heard before that pickup blew past your shoulder. BikeTalk shouts it for you. Pair any Bluetooth cycling radar and BikeTalk speaks approaching vehicles through your headphones. No beeps to decode. No screen to glance at. Just the words riders have been using since forever: "Car back, 80 feet." "2 cars, 60 feet." "Wicked fast!" "Clear." ONE RADAR. EVERY PHONE IN RANGE. This is the part no other app does. • Riding solo? Your radar, your phone, your callouts. • Riding with a partner or in a group? Only one rider needs to own a radar. Every other phone in Bluetooth range hears the same callouts — no pairing between phones, no setup. The rider at the front of the peloton has the radar; everyone behind hears every car. • Add the intercom and you can talk to each other too. BikeTalk listens to the radar's open Bluetooth broadcast — read-only, no configuration, no control. Any phone within range hears it. GROUP INTERCOM When you want to talk to your group, tap the mic or use your headphone's play/pause button. Multiple riders can speak at once — it's a conversation, not a walkie-talkie. Peer-to-peer over Bluetooth and Wi-Fi (the same technology as AirDrop). No cell signal. No account. No server. ~60 metres line-of-sight. Hands-free. Works with AirPods, Shokz, bone conduction, helmet speakers, or any Bluetooth audio. FOR RUNNERS TOO Flip on Running mode and BikeTalk becomes an eyes-free running companion: • Pace instead of speed — on screen, and spoken in your ear as often as you like • Grade-adjusted pace, so a hill at honest effort doesn't read as a lost split • Pair a Stryd or any Bluetooth footpod for pace and cadence • Effort targets: set your heart-rate, power, and pace bands and hear one word when it matters — "push," "ease," "hold." Heart rate is the safety ceiling: blow past it and you'll hear "ease," no matter what the pace says. • Recovery floors keep the coach quiet between intervals Group run? The intercom works on foot exactly like it does on the bike. DESIGNED FOR YOUR POCKET BikeTalk is built to work from your pocket. Drop your phone in your jersey, put on your headphones, and go. Everything important comes through the audio — radar callouts, group chat, heart rate, pace, weather. You don't need to look at your phone. If you do mount your phone on your bars, even better — the screen below is the bonus view. But it's not required. THE COCKPIT The main screen is everything you'd put on a bike computer, sized for glance-able reading at road speed: • Heart rate — pair any standard Bluetooth HR strap • Power and L/R balance — pair any standard Bluetooth power meter • Speed or pace, location, weather, route home • Pass count, duration, start/restart/end controls • Big numbers, dark UI, designed for sunlight and motion Phone on the bars or in your pocket. Either way, you're set. SUPPORTED RADARS Works with standard Bluetooth cycling radar tail lights, including RTL515, RVR315, RCT715, eRTL615, RearVue 820, and Bryton Gardia. CHOOSE YOUR VOICE • Boston Cop (default) — "Wicked fast!" • Boston Woman • Neutral default PRIVACY No account. No sign-up. No tracking. No analytics. No ads. No subscriptions. No in-app purchases. Audio between riders is peer-to-peer and never recorded. Free. Made by a cyclist in Boston who got tired of beeps. SAFETY NOTE This is a backup awareness layer. Always rely on your mirror, head-checks, and head unit display first. Privacy Policy: https://biketalk.app/privacy.html Terms of Use: https://biketalk.app/terms.html

Since a few riders have asked, here's exactly what's going on. What actually controls your board isn't this app, and isn't AI. The VESC firmware runs the motor, and the Refloat package — open-source, human-written firmware on the board — does the real-time balancing many times a second. That's what controls your ride. FlowState runs on your phone, outside that loop: it displays the data Refloat broadcasts and, only when you choose, sets Refloat's settings within its own limits. Your board rides exactly the same whether your phone is connected, pocketed, dead, or absent — and nothing is "AI-controlled" while you ride. Claude helped write the code; it doesn't run while you ride. In short: FlowState monitors and configures; Refloat controls. FlowState has been thoroughly tested on real hardware and stays within safe boundaries: - It only reads and writes the Refloat package's settings — the same values you can adjust in VESC Tool, Float Control, or Floaty — always within the ranges Refloat allows, using Refloat's own format. - It does not modify VESC firmware or your motor configuration. No firmware flashing, no motor detection, no FOC, current-limit, or hardware changes. - It cannot push values outside Refloat's limits, and it does not bypass your board's built-in fault and safety systems. - Battery/BMS: the only battery-management change it can make is the charge limit — locked to the specific BMS model and firmware versions it's been tested against, and disabled on anything else. Note: FlowState doesn't double check your VESC/motor configuration like Float Control — after setting up or reconfiguring your board, double-check it in Float Control before riding. FlowState was inspired by Float Control and Floaty and owes a lot to them — sincere thanks to their creators for paving the way for tools like this.
