Testing Engwe's Dual Battery System: 100-Mile Range Challenge

I added the second battery to my Engwe Engine Pro. Here's what I learned.

The Setup

Single Battery: 48V 16Ah (768Wh) Dual Battery: 48V 32Ah (1,536Wh) Cost: +$599 for second battery

Real-World Range Test

Test conditions: 200lb rider, moderate pedal assist (PAS 3), mixed terrain

Single battery: 47 miles before cutoff Dual battery: 94 miles before cutoff

So yes, 100-mile range is achievable with light pedal assist.

When Dual Battery Makes Sense

Yes if:

• Multi-day bikepacking trips
• Long commutes (30+ miles one-way)
• Remote trail riding

No if:

• Daily commute under 20 miles
• Access to charging at work

Installation

Takes 15 minutes. Batteries hot-swap seamlessly. No tools needed.

Weight Impact

Second battery adds 7lbs. Noticeable but not a dealbreaker.

Bottom Line

For serious riders, the dual battery system transforms the Engwe into a true adventure bike. For casual riders, single battery is plenty.

Awesome test, William! Your numbers totally confirm what I suspected—getting close to 100 miles requires efficient riding (like PAS 3), but it's clearly possible if you optimize. The key takeaway for anyone considering this is managing which battery drains first; are you running them parallel so they share the load, or do you have a switch to run one down completely before switching to the fresh one? That second method usually maximizes total distance.
