Powering EVs, Drones & Robotics — Even in Extreme Cold
At Bicycle Motor Works, we don’t just build eBike batteries — engineer high-performance power systems designed to support a wide range of electric applications. From EV conversions and drones to robotics and specialty projects, our battery packs are purpose-built to deliver unmatched performance, reliability, and cold-weather resilience.
If your project demands serious power, durability, and consistency — especially in freezing temperatures — you’re in the right place.
Engineered for Performance Beyond eBikes
While many battery builders focus solely on recreational eBikes, Bicycle Motor
Works designs professional-grade battery systems capable of powering:
• Electric vehicles (EV conversions & specialty builds)
• Industrial and research drones
• Robotics & automation projects
• High-current experimental systems
• Off-grid and specialty electronics
Every pack is custom built in the USA, engineered around your project’s:
✔ Voltage requirements
✔ Continuous & peak amp draw
✔ Physical size constraints
✔ Weight limits
✔ Operating temperature range
Built Better: What Sets Bicycle Motor Works Apart
We outperform competitors because we never cut corners.
Pure Copper Busbars
Lower resistance = less heat = higher efficiency
We use solid copper, not nickel-plated steel found in mass-produced packs.
High-Quality BMS (Battery Management Systems)
Our packs use high-current rated BMS with:
• Overcharge protection• Over-discharge protection• Thermal monitoring• Short-circuit protection
Built for demanding applications — not hobby builds.
Certified Tier-1 Cells Only
We exclusively source premium, tested cells from:
• Molicel• Samsung• LG• Reliance• Ampace
No rewraps. No unknown imports. No downgraded batches.
Professional Assembly & QC
Every pack is:
✔ Balanced
✔ Stress tested
✔ Inspected
✔ Verified before shipping
Designed for Cold-Weather Performance
Cold temperatures expose weak battery builds. Voltage sag, reduced capacity, and internal resistance cripple performance — especially for drones, EVs, and robotics.
That’s why Bicycle Motor Works specializes in winter-ready battery engineering.
Top Cold-Weather Cells We Recommend
These cells were selected for high current output and thermal stability:
Molicel P45B
• Excellent cold discharge behavior
• High continuous current rating
Molicel P50B
• Industry-leading power density
• Strong voltage retention in cold
Ampace JP40
• Designed for heavy-load stability
• Proven winter performance
Ampace JP50 (NEW)
• Next-gen chemistry
• Improved cold response & efficiency
Reliance RS50
• Ultra-durable• Outstanding thermal behavior
• Built for extreme applications
These cells maintain higher voltage under load, reduce sag, and recover faster — making them ideal for:
✔ Winter riding ✔ Cold-weather drones ✔ Outdoor robotics ✔ EV builds
Custom-Built for Your Project
No two projects are the same — and neither are our batteries.
We custom design packs based on:
• Voltage• Amp draw
• Space constraints
• Application type
• Environmental conditions
If you’re operating in cold climates, we’ll engineer your pack for:
✔ Thermal efficiency
✔ Cold-start reliability
✔ Safe discharge limits
✔ Long-term durability
Work Directly with Battery Engineers
When you contact Bicycle Motor Works, you speak directly with battery specialists — not sales reps.
We help you:
• Select the right cell chemistry
• Size your pack correctly
• Optimize performance
• Ensure safety compliance
Your project deserves real engineering — not guesswork.
