In 2019, we didn't pick a stock frame and bolt a battery onto it. We started with the battery and designed the frame around it.
Frame designed around battery cavity
Maximum battery volume in the triangle
Purpose-built, not retrofitted
Frame designed battery-first
First 20Ah models ship — Rook, Colt, Shred
Battery standardized across all models
UL 2271 + UL 2849 certified
14Ah killed — 20Ah is the only option

| Brand | Battery | Price | $/Wh | What You're Missing |
|---|---|---|---|---|
| Surface 604 Rook | 960Wh | $1,999 | $2.08 | Nothing — biggest battery + torque sensor + 3yr warranty |
| Aventon Level 3 | 708Wh | $1,899 | $2.68 | 31% less battery, more expensive |
| Velotric Discover 3 | 691Wh | $1,999 | $2.89 | 39% less battery, most expensive per Wh |
| Ride1Up Vorsa | 720Wh | $1,495 | $2.08 | 33% less battery, 1yr warranty only |
Torque sensor vs cadence sensor:The Lectric XP4 costs less — but it uses a cadence sensor instead of a torque sensor. That's the difference between an on/off switch and a volume knob.
Warranty:Lectric's 1-year warranty vs Surface 604's 3-year frame + 2-year parts warranty.

Battery Certification
Overcharge protection, short circuit protection, thermal runaway prevention, impact resistance, and environmental stress testing.
UL 2849
Complete E-bike Certification
Motor, controller, wiring, charger, and battery all tested together as an integrated system. We certify the whole bike.
With e-bike battery fires making national headlines, we invested in both UL certifications — not because we had to, but because your safety isn't negotiable.
