The technology inside
Why mid-drive is fundamentally different
Hub motors bolt onto a wheel and brute-force it forward. Mid-drive sits at the pedal crank — exactly where your legs push — and works with your gears. The result is night-and-day different on Indian roads.
⚙️
Works through your gears
In low gear on a slope, you get 3–4× more torque at the wheel than a hub motor at the same wattage. Your Atlas cycle suddenly climbs flyovers it couldn't before.
⚖️
Central weight — perfect balance
Motor sits at the bottom bracket, dead center. Hub motors unbalance the wheel. With TAV, the handling feels exactly like your original bike.
🔋
Smarter power use = longer range
Mid-drive leverages your drivetrain. At speed in high gear, the motor barely works. On hills in low gear, it multiplies your effort. Result: 100 km from a 5.6Ah battery.

How to install your TAV kit
Step 01 of 05
Remove pedals & bottom bracket
A standard 15mm spanner is all you need. The pedals and existing BB come off in under 5 minutes on any Indian cycle — no special tools, no experience required.
⏱ ~5 minutes
15mm spanner
Tool needed: 15mm spanner (standard household tool, not included)
Step 02 of 05
Fit the TAV motor unit
Slide the motor into the same BB shell your old bracket came out of. Tighten with the included mounting tool. Zero frame modification — no drilling, no welding.
⏱ ~8 minutes

Mount battery & connect cables
Strap the battery to the downtube or carry it in a bag. Just 3 cable connections — all color-coded connectors that only fit one way. Impossible to get wrong.

Step 04 of 05
Attach throttle & speed sensor
Clamp the thumb throttle to your handlebar. Attach the small magnet to a spoke. That's your cadence sensor done — the motor now knows when you're pedaling.

Questions answered
Before you buy
No frame modifications at all. The TAV kit replaces the bottom bracket — the same threaded shell your existing BB screws into. It comes out, the TAV motor goes in. Same thread, same shell. No drilling, no welding, fully reversible.
No. Under the Motor Vehicles Act, electric bicycles with motors under 250W and speed below 25 km/h are classified as bicycles — not motor vehicles. No registration, no licence, no insurance required.
The 5.4Ah battery gives around 25 km on full throttle; the 8Ah gives around 40 km. On PAS 1 (minimum assist) range is higher. The battery charges via a standard wall socket in 3–4 hours. The charger is included and the battery is removable.
If your bicycle has a standard threaded bottom bracket shell (68–73mm BSA thread), the TAV kit fits. This covers roughly 95% of bicycles sold in India including Hero, Atlas, BSA, Firefox, Hercules, Decathlon, Montra, and most other brands.
Yes — completely normally. The motor disengages when you're not using it. The weight addition (about 3.2 kg for motor + battery) is noticeable but not prohibitive, and the mid-drive placement keeps the handling natural.
With mid-drive, fixing a flat is exactly the same as on a normal bicycle. The motor is at the crank, not the wheel — so you remove the wheel exactly as you would without the kit. Hub motor owners have to disconnect motor wires before removing the wheel.
The motor unit carries a 1-year warranty against manufacturing defects. The battery carries a 6-month capacity warranty. WhatsApp support is available Monday to Saturday, 10am–6pm IST for any questions or issues.
The kit is designed for self-installation using only the included tools. Most customers complete it in 30–45 minutes on their first attempt. A step-by-step guide is included, and our WhatsApp team guides you live during installation if you need it.
