How this e-bike scores for different riding styles
The 481Wh capacity and 750W motor compatibility provide moderate performance potential. However, 36V systems typically deliver less power than 48V or 52V high-performance setups.
The battery itself is compact at 15.4 inches tall and weighs less than most batteries. However, it's just a replacement part, not a portable e-bike solution.
This is a replacement battery, not a complete e-bike. It lacks motor, frame, wheels, and all components needed for commuting. Only useful if you own a compatible Heybike Cityscape.
This battery replacement enables leisure riding only if you already own a compatible Heybike. It cannot function as a standalone recreational product.
As a standalone battery accessory, this cannot be used for off-road riding. It only provides power storage for compatible e-bikes already owned.
A replacement battery provides no cargo utility on its own. It only powers compatible e-bikes that may or may not have cargo capabilities.
Our Verdict
The YS YOSE POWER DF 36V 13Ah is a purpose-built replacement electric bike battery for Heybike Cityscape riders who need a like-for-like swap. Its 481Wh lithium-ion pack supports pedal-assist ranges of 47 to 97 miles depending on terrain and rider weight — above-average endurance for city commutes and light trail use.
The built-in 20A BMS handles overcharge, overdischarge, short-circuit, and thermal protection, keeping acceleration and torque delivery stable through the motor's 750W ceiling. Compared to 48V systems, the 36V voltage produces lower watt output, which trims top-end performance on hill climbing and reduces torque at high cadence. Riders upgrading to a 48V e-bike will need a different battery entirely.
At $239, the YS YOSE POWER DF 36V 13Ah sits at roughly the mid-range price point for brand-specific replacement batteries. The 18-month warranty on cells and 30-day return window offer reasonable purchase comfort. The 390.5mm x 111mm x 75mm form factor slots directly into Cityscape battery mounts with no modification needed.
For Heybike Cityscape owners prioritizing a reliable, compatible replacement over maximum watt output, this battery delivers solid value per mile. Riders seeking performance gains or broader compatibility should consider a full bike upgrade instead.

- At $239, cost-per-Wh is $0.50, roughly 25% higher than generic 36V packs of equivalent capacity
- 20A maximum discharge current limits burst power delivery with motors drawing above 720W peak
