BORN IN
THE 415

Precision
Tight specs, tight tolerances, zero compromise.

Dropped the Bafang M620 Ultra into my Yeti SB130 and the result is absolutely insane. Climbs that used to wreck me are now pure fun โ€” the torque is savage but the power delivery feels natural. 415 packed it perfectly and it showed up in two days. Best money I've spent on any bike part, ever.

I've ordered from six different suppliers over the years and 415 is on another level. The 52V triangle battery arrived fully charged with the BMS already configured. The Bluetooth app actually works and shows real cell data. Fast shipping, zero issues, and they answered my wiring question in under an hour. Customer for life.

Swapped my cheap rear hub for the QS 205 and the difference is night and day. Silent, fast, and not even warm after a 30-mile commute. The torque sensor BB they recommended was the right call โ€” it feels like a proper mid-drive now. 415 knows their stuff and they don't try to oversell you.
