Hammerhead SHARK E-Bike 29 Inch Wheel – Mid Drive Motor

Contribute To Sustainability

Electric bikes are great for short commutes to work or running errands. Most often you will get to your destination quicker by avoiding traffic and at the same time cutting down on carbon emissions and pollution.

Easier To Ride

Allow yourself a smoother ride and reduce stress on muscles and joints. Pedal assist will help you on steep inclines or rough terrain making the journey easier and more enjoyable.

Improved Physical And Mental Health

Cycling on an E-bike is more accessible and people are more likely to do it because it's easier, getting about the same workout with less the effort. For those who live a more sedentary life, an e-bike gets them moving and out in nature. The change in scenery, and fresh air helps reduce stress, improve mood, provides for a more restful sleep and increases productivity.

The Fun Factor

Getting to your destination a little quicker, feeling the wind against your face, contributing to the environment and generally feeling healthier, there is definitely an element of fun riding an E-Bike

Electric bikes are becoming more and more popular not only for cyclists but also for leisure seekers, commuters and delivery services. With so many options available and different types of electric bikes on the market the question is, which bike is right for you? Consider some of the pointers below before buying your E-Bike.

Style

Firstly you need to consider what style of bike you are looking for. Types of E-Bikes range from Step Through bikes with a classic design, crossbar versions, mountain bikes or the ever more popular folding bikes. Then there are other considerations like hybrids which can be used on or off road. Wheel size can also be an important factor with a smoother ride on a larger sized wheel. Generally a 26” or 24” wheel will be better for off-road than a 28” wheeled bike which would be better on the road depending on the width and tread of the tyre. The step through bikes are easier to mount and better for road use where an Electric Mountain bike (E-MTB’s) is perfect for more challenging terrain off the road or trailing. Folding E-Bikes have the obvious advantage of saving space when storing or transporting.

Distance

Depending on the terrain, riders weight and weather related conditions, the ampere rating (AH) or watt hour rating (WH) will determine the distance your new E-bike can travel on a charge. Below is a list of approximate distances you can get on the various batteries sizes:
10AH or 375WH Battery will give an approx. distance of 27-35 miles
16AH battery will give an approx. distance of 60 – 70 Miles

Legalities And Power

In the UK the legal limits for E-Bikes being used on the road are 15.5mph and the motors must be limited to 250w. The battery voltage is an important consideration so if you need a powerful hill climber a 36v battery and a 250w motor would be recommended.

Size Guide

Choosing the size of your new electric bike depends on various factors including your height, inside leg measurement and riding style, however almost any size bike can be configured to give you the most efficient and comfortable ride. Below is some guidance on choosing your bike.

196cm+ / 6' 5"+                               91cm / 36"          62, 63cm (XX Large)        

Drive Systems

There are two main drive systems with electric bikes, either central crank drive or hub drive systems.

A crank driven motor is located in the middle of the bike frame and propels the bike through the chain with the use of the rear wheel gears. This is a highly efficient system because it can increase its own torque and allows the bike to climb up very steep hills. These crank driven bikes are known as pedelec bikes meaning it will only work when the rider is pedalling by rotating the cranks. Being equipped with a torque sensor, they are more intuitive than hub driven motors because they recognizes when the rider is putting effort on the cranks. The more the rider puts effort on the crank, the more power is supplied by the motor and the faster the bike goes. There are various Crank drive systems available and the ones to look out for are Bosch, Yamaha, Shimano and Panasonic.

With a hub driven systems the motor is located in the hub which propels the wheel independently from the bike chain or cassette. Hub motor systems can be driven either by pedal assist mode or via throttle control. Many models offer a selection of different levels of pedal assist modes and the power will come in based on the level set whilst pedalling. Throttle mode is a twist and go or thumb throttle which does not require the rider to pedal. This system is great for riders who do not want to worry about the need for exertion. Hub driven E-bikes are a more effortless means of cycling an electric bike.

Once you have placed your order we will be in communication with you about the estimated delivery date.

Please see the relevant delivery information for each brand on the product page.

Please see the Description tab for the exact warranty on each model. Because some bikes are 98% built and tested before delivery, with only the handlebars needing to be tightened and pedals screwed in, the chances of receiving a faulty bike are vastly reduced.
