Top speed by kit
Rough real-world numbers with the right gearing:
- BBS02 750W โ 25+ mph, the fastest street-legal kit available in the U.S. (best top speed with a larger chainring like a 52T plus your rear cassette).
- BBSHD 1000W โ SERIOUSLY FAST, 30+ mph. It has enough grunt to loft the front wheel โ this one is off-road / private-property only.
- Front Hub 500W โ 20+ mph.
What affects your real speed
Actual speed depends on chainring/sprocket size, rider weight, terrain, wind, tire diameter, and how much you pedal, so we can't guarantee a specific number. Want to estimate your setup? Plug your wheel size, chainring, and smallest cassette cog into any online bike-speed calculator such as bikecalc.com. And remember โ top speed is programmable, and staying within your local e-bike laws is the rider's responsibility.
