Frequently Asked Questions
What is the difference between Rear Freewheel and Rear Cassette kits?
The Rear Freewheel motor has male threads designed for screw-on multi-speed freewheels (typically 6, 7, or 8 speeds). The Rear Cassette motor features a splined freehub body compatible with modern slide-on gear cassettes (8, 9, 10, or 11 speeds), allowing you to retain your bicycle's existing high-end cassette and derailleur setup.
How do I select the right wheel size for my bicycle?
Check the sidewall marking of your current bicycle tires (for example 26 × 1.95, 27.5 × 2.1, or 700 × 28C). Order the kit that matches your tire diameter. The double-wall alloy rim will accommodate common tire widths from 1.5'' to 2.35''.
What battery should I use with this 500W kit?
A 36V 500W kit requires a 36V lithium battery, while a 48V 500W kit requires a 48V lithium battery. To support the 26A peak current without voltage sag, select a battery with a continuous discharge rate of at least 26A–30A (typically 13Ah to 20Ah capacity for 40–80 km of range).
Can I use hydraulic brakes with this conversion kit?
Yes. The kit includes external inline brake cut-off sensors that can be attached to your existing hydraulic brake levers without bleeding or replacing your hydraulic brake system.
Does E Smart Way provide warranty and free shipping?
Yes, all conversion kits ordered through E Smart Way include responsive customer support, manufacturer warranty coverage, and free storewide shipping.
