Huge Range Of Electric Mountain Bikes For Sale

At 99 Bikes we have a wide range of Mountain bikes for sale Australia wide. Get more out of cross-country riding, climbing and downhill trails with an electric mountain bike. The natural feeling assistance makes these riding types more accessible to riders of varying ages and abilities.

For those starting out, more pedal power means less exertion and more time to enjoy the ride! It also turns uphill climbing from an often painful chore into becoming an engaging part of the overall experience. Experienced riders exploring more advanced trails will appreciate the suspension and grip of a mountain bike, which provide a greater level of comfort and control while going downhill, compared to regular mountain bikes.

Reasons to Buy an Electric Mountain Bike?

• Powerful motors open up new territory and trails riders may not have been able to reach before.
• WIth ascents being an absolute breeze, riders can score extra runs before tiring out or running out of time.
• Paired with wider tyres, riders can push through tough terrain with more stability and control

Choosing an Electric Bike

Choosing an Electric Mountain Bike can be a big decision. Electric trail bikes range from $2,000 to $20,000 and there is a wide range of models to choose from.

There are 2 main types of EMTB's, hardtail mountain bikes which are for new riders or riders who want to use the bike for multiple purposes like commuting. Dual suspension electric bikes feature suspension at the front and back for the bike. Full suspension e bikes are designed mainly for use on mountain bike trails.

When choosing an electric mountain bike, the Motor and battery are definitely the most important component to understand as it will generally be the differentiating factor when it comes to weight, price and how the bike feels to ride.

Dual suspension electric mountain bikes are quite heavy when compared with a regular dual-suspension mountain bike, most models weigh in around 20-25kgs.

Understanding EMTB Motors

Power of Battery = Volts - The simplest way to think of volts in terms of E-Bike performance is the 'horsepower' of the battery/motor. E-Bike batteries typically come in 24V, 36V and 48V options.

Battery Capacity = Amp-hours - Amp-hours are the most common unit for battery capacity in E-Bikes. The best way to think of them is the size of the 'gas tank'. The more amp-hours (Ah) a battery has the longer range you'll get from your E-Bike.

Battery Run time = Watt-hours* - Sometimes battery packs will be quoted in Watt-hours, eg. Bosch Batteries being available in PowerPack300 and PowerPack400 options, both referring the Watt-hour capacity of the battery.

Watt-hours is generally a better indicator of range as it takes into account the volts and amp-hours of the battery. ​

For Example:

Bike #1 has 24 Volts and a 20 AH battery = 480 watt hours
Bike #2 has 48 Volts and a 10 AH battery = 480 watt hours.<
Both bikes have similar energy on board. And if they have roughly equal motors and riders, they will probably perform in a very similar fashion.

Motor Power Output = (Torque measured in NM) - Torque is the measure of power that's being put through the cranks. High torque motors will be able to give the most assistance but will also drain the battery the fastest.

Once you start putting load onto the pedals, sensors detect the amount of load you're putting in and adjust the amount of assistance delivered to help you pedal. Most full suspension bikes will come with a motor that outputs 80-90nm which translates to a massive 340% assistance.

Bikes like the Specialized Turbo Levo utilise a lower power motor and smaller battery to produce a lighter bike with the same estimated range as a big power, big battery bike. The only drawback is you get less assistance and have to rely on your leg power more.

The range that an electric mountain bike can achieve is a complex equation with all the above terms combined with external factors like terrain, rider weight, tyre pressure, wind speed and more.

This is how bikes like the Specialized Turbo Levo can utilise a lower power motor and smaller battery to produce a lighter bike with the same estimated range as a big power, big battery bike.

Features of E Mountain Bike

Most electric mountain bikes come standard with a Mid-drive motor. This motor position offers better weight distribution and a more natural pedalling experience.

Due to the terrain and demanding power output, EMTB motors tend to best the most powerful on the market with most offering up to 85nm of torque.

Trail Mode - Most modern electric bike motors like the Bosch Performance Line CX feature Trail mode, which uses in-built sensors to read the terrain and automatically adjust the power output to give you the perfect amount of assistance and let you focus on the trail ahead.

Walk-assist - Recently manufacturers like Bosch has added walk-assist as a feature on their motors. Walk assistance can make it easier for you to push the eBike up steep or muddy hills. The speed of this function depends on the selected gear and can reach a maximum of 6 kph.
