How much torque does it have?

Where it falls short
The Big Dog's estimated range is far below its claimed range. You get 48 km estimated, not 129 km. That is a 63% difference. Also, the price is high at 3599 USD, which is 140% above the median. You pay a premium for the torque and cargo capacity.
Who should buy it
The Big Dog is for riders who prioritize torque and payload over range. It is a fast-class cargo bike with a 181 kg payload. You can carry heavy gear, but you will need to plan for shorter trips.
- You haul heavy loads and need strong acceleration.
- You ride on hilly terrain and want high torque.
- You accept a shorter estimated range and can charge often.
Look elsewhere if you need long range or a lower price. The estimated range is 48 km, which may be too short for commuting. Also, the price is high compared to other cargo bikes. Consider your needs before buying.
