Frequently Asked Questions

Speed depends on the make and model. Most E-bikes are restricted to 32km/h, however some models are capable of up to 45km/h. The same is true of E-scooters we stock scooters that range from 25km/h up to 75km/h.

Yes we have a full workshop at the rear of our store with certified bike mechanics. We are able to test and diagnose Bosch and Shimano E-bikes drive systems as well as repair E-scooters. We can also work on most brands of non E-Bikes.

To be considered a bicycle and not a moped or scooter an E-Bike must fall under the following definition; “a power assisted cycle with an auxiliary electric motor, a maximum power not exceeding 300W and one that is designed to be primarily propelled by the muscular energy of the rider.”

In order to meet the requirements for a low-powered vehicle, the wheels must not exceed 355mm and the motor must have a maximum power output not exceeding 300W this is calculated by the Amp output of the controller multiplied by the voltage of the battery and not the max output of the motor. Many of the high powered scooter sold at E-Mega Store fall outside this category and therefore E-Mega Star sell these products for private land use and not for public roads or pavements. We recommended all our customers refer to the NZTA guidelines for current regulations.

Using electricity stored in the bikes battery the motors give assistance to your pedaling to make the riding easier. Some E-bikes even come with a throttle so you don’t have to pedal at all! There are two main types of motor; hub motors and mid drive motors. Hub motors are positioned inside the rear wheel and actively turns your wheel. Mid drive motors are positioned on the bottom bracket and help turn your pedals. Mid drive motor tend to have a more natural feeling and also tend to be more efficient. 

Although the Wattage of E-bike motors doesn’t vary much between brands and models, with most motors falling between 250W and the NZ legal max of 300W, the torque of the motors does. Generally motors have a torque between 40Nm and 85Nm. The more torque your motor has the more assistance it can give you when tackling steeper climbs. The trade off with extra torque means your range does decrease and therefore it’s important to tailor the motor and battery combo with the riding you’re most likely to do.

Range is dependent on a number of factors including battery capacity, motor, rider weight, cadence, road conditions and bike and scooter style (mountain bikes have a lower range than road bikes due to increased frictions and lost energy). With E-Bikes you can expect a range between 40km and 150km and with E-scooters between 15km and 100km.

Not necessarily, with the same motor and bike style a larger capacity battery will indeed have a further range but different motors will have different efficiencies and therefore the whole package needs to be considered.

Wh are a unit of power and Ah are a unit of electrical charge. The best way to compare battery capacities is to use Wh as they are independent of the voltage of the battery.
Ah is a unit of electrical charge. At a given voltage the larger the Ah of a battery the larger capacity your battery has. The capacity is however dependent on the battery voltage and a 10.4Ah battery at 36V has a lower capacity than a 10.4Ah battery at 48V.
Watt hours are independent of voltage and can be found by multiplying the voltage of a battery by the Amp hours (36V x 10.4Ah = 374Wh).
