Why Mid Drive? Why VOLT?!

You don't see motors in motor cycle wheels. You don't see motors in car wheels. Wheel hub motor ebikes are obsolete.

Mid Drive motor is a great new eBike invention. The power is connected to bike gears! And gears facilitate effortless hill climbing as well as high top speeds. This range of control is fun for riding. Also, keeping wheels light makes the bike nimble for off road use. Hub motor riding feels silly in comparison.

At VOLT, We work vigorously on assembling electric bikes and our engineering practices. We are constantly developing new products as we are obsessed to create better products.

Since 2018, Volt Electric Bikes have been approved to be Australian Made. Our two workshops in Sydney & Melbourne provide the national support to our customers over warranty issues and repair service.




Bicycle Size issue & Gears

Most motorcycles or scooters come in one size only. Ebikes with a powerful motor eliminate the need for different bicycle sizes. As long as sitting on the bike feels comfortable, a bit small or a bit large does not compromise the riding experience.


Similarly, most cars or motorcycles would not have more than 5 gears, it is true for ebikes as well. E-bikes actually do not need more than 5. We have chosen 8/9 speeds because no manufacturer is making good 5-7 speeds drive systems.


There are many styles for bicycles. There really should only be a couple for ebikes. The riding position should be more upright for maximum comfort while exercising. The bike should maneuver around corners easily. Tyre should be for all terrain and wide for grip & sturdiness.  The frame should be heavy duty to absorb impact. Brakes must be powerful. Like all things, it should also look pretty.




Volt eBikes are the best electric bikes made in Australia.
