Where it falls short
The W77's main drawback is its weight. At 43.2 kg, it is 26% heavier than the median. That extra mass makes it harder to handle off-road and more tiring to push if the battery dies.
Who should buy it
This bike is for budget-focused riders who want an e-MTB for casual trails. It is not for those who need to carry it upstairs or ride aggressive terrain.
- Riders who want the lowest entry price for an e-MTB.
- Commuters who value a large battery for long trips.
- People who ride mostly flat, smooth paths and don't need high torque.
Look elsewhere if you need a lighter bike or more torque. Also consider a model with a published warranty, since the W77 does not list one.
