What Is an Electric Cycle Conversion Kit?
An electric cycle conversion kit is a set of components that transforms a standard manual bicycle into a battery-powered electric bike. Unlike buying a new e-bike, a conversion kit lets you reuse your existing frame, saddle, and gearing — dramatically reducing cost while achieving identical performance.
Types of Electric Cycle Conversion Kits
1. Rear Hub Motor Kit (Most Popular)
A motorised wheel replaces your existing rear wheel. The motor is hidden inside the hub — invisible from the outside. This is the most common type because:
- Easy DIY installation (no frame modification needed)
- Compatible with all standard bicycles (26", 27.5", 29")
- Lowest cost — starting at ₹9,990
- Handles Indian road conditions including potholes and gravel
All Voltebyk conversion kits use rear hub motors for maximum compatibility and reliability.
2. Front Hub Motor Kit
Motor placed in the front wheel. Simpler to install but offers less traction on inclines — not recommended for Indian terrain with frequent hill gradients.
3. Mid-Drive Motor Kit
Motor positioned at the crank (bottom bracket). Delivers the best hill-climbing performance but requires professional installation, costs ₹40,000+, and has limited compatibility. Not practical for most Indian cyclists.
Wheel Size Compatibility
Voltebyk hub motor kits support the following wheel sizes:
- 20" — Folding bikes, compact commuters
- 24" — Children's bikes, step-through frames
- 26" — Standard MTBs, most Indian bicycles (Hero, Atlas, BSA)
- 27.5" — Modern trail bikes
- 28" / 29" — Road bikes, hybrid cycles
36V vs 48V: Which Voltage System Should You Choose?
| Spec | 36V System | 48V System |
|---|---|---|
| Top Speed | 25 kmph | 35–45 kmph |
| Legal (India) | ✅ No registration | ❌ Requires registration |
| Price | ₹9,990+ | ₹25,000+ |
| Best For | Commuters, city riders | High-speed enthusiasts |
For 95% of Indian commuters, a 36V kit is the right choice — it's legal, affordable, and more than fast enough for city roads.
What to Check Before Buying
- Wheel size — measure your current rear wheel diameter
- Axle width — standard rear dropout is 135mm for most Indian bikes
- Frame material — steel frames are the most compatible; carbon frames require special care
- Disc vs rim brakes — Voltebyk kits support both
- Battery type — always match battery voltage to motor voltage (36V motor = 36V battery)
Installation Overview
A Voltebyk rear hub kit can be installed in under 2 hours with basic tools. The full step-by-step process is documented in the official conversion kit guide. Key steps:
- Remove the existing rear wheel and replace with the motorised hub wheel
- Mount the battery pack to the frame or rear rack
- Connect the controller to the motor using colour-coded plugs (no soldering)
- Install throttle and brake levers on handlebars
- Attach the display unit and test all connections
