Recently I happened to see them in Sylvia park. Their bikes are pretty cool, with large battery, water-resistant and decent price.
They also have a physical store.
Compare to the other brands that often posted on cheapies, this is obviously a much better choice. That is why I am posting it.
They also have some other models on their website.

What is a water resistant bike? You can't ride it in the rain? Those specs look pretty sus based on battery capacity and motor power.
