All Terrain Electric Bike: How to Choose for Mixed Terrain

Most outdoor rides are not consistent in the type of surface that they are riding on.

The route can start on a paved road, then head onto a dirt road, then onto a rocky road and then onto a mud road. What may feel stable on asphalt may not be the same on a soft, steep or erratic surface when riding an electric bike.

That is why it's not about the robust motor or aggressive look when talking about an all terrain electric bike. The changing terrain requires its tires, suspension, brakes, gearing, battery and frame to all function together.

There are a variety of different ways of solving the off-road riding problem with an electric bike, from the Zoulaglide's little fat-tire machines to the larger bikes that are ideal for long outdoor rides.

 

Keep It Real; Ride the Terrain You're On

Not all electric bikes can handle all trails – be aware of the “all terrain”.

Requirements for a rider on a paved road and a maintained gravel road are different than for someone riding on a soft sand, a loose stones, a muddy track, or repeated steep gradients.

When comparing models, break up the route you are planning into the surface types that you are likely to run into:

lPavement and cycle paths;

lcompact gravel;

lloose stones;

lgrass/woodland trails;

lmud or wet ground;

lon sand, snow or other soft surfaces;

lMild or frequent slopes.

Take into account the frequency of occurrence of each surface as well. A very heavy off-road setup could cause unnecessary rolling resistance if 80% of the journey is to be done on pavement. Where loose ground is frequent, wider tyres, and greater traction are more important than is minimum weight.

Primary Surface	Tire Priority	Suspension Priority	Riding Setup
Pavement + Light Gravel	Moderate width, low rolling resistance	Basic front comfort	Medium pressure, moderate assist
Loose Gravel	Open tread and lateral grip	Controlled front movement	Smooth assist, relaxed steering
Muddy Trail	Self-clearing tread	Stable wheel contact	Lower speed, progressive power
Sand or Snow	Fat-tire flotation	Comfort-focused	Lower approved pressure
Hilly Mixed Route	Traction under load	Reduced front-wheel bounce	Low gearing, battery reserve

 

Tire Design Controls FPC

The tires define the way in which motor power, braking and steering input is transferred to the ground.

The narrower tyre will tend to roll easily on hard surfaces, but will sink or flex on softer surfaces. Fat tyres will provide a larger contact area and in gravel, sand, mud or snow can be beneficial for flotation, grip and balance at lower speeds.

Just width isn't enough. It is also advisable for the buyers to check:

lTread pattern & tread depth;

ltire pressure range;

lpuncture protection;

lsidewall support;

lwheel diameter;

llocal replacement availability.

Reducing the pressure will improve traction and comfort on low friction surfaces and improving pressure should generally improve rolling resistance on high friction surfaces. Pressure should never be outside of the tire manufacturer's recommended limits.

Planning for replacement is also important. When it comes to choosing an electric bike tire, Zoulaglide's offerings are a helpful guide to the tread, durability and future maintenance.

 

Suspension should not only absorb bumps, it should keep the movement in check.

Front suspension can both minimize side-to-side forces felt by the rider's arms and enable the front wheel to stay on the ground in rough terrain.

But, it's not just about having a suspension fork, it's about suspension quality. Too soft a setting can result in the bike diving when braking and too hard a setting can not help on bad surfaces.

Suspension should provide support for:

lrecreational/ mixed terrain riding.

lSteering that is stable on stones and shallow ruts;

limproved front-wheel contact;

lreduced rider fatigue;

lBraking in a controlled manner on an uneven surface.

Fat tyres may offer some extra cushioning, but don't compensate for good suspension. It is important to think of the tire pressure, suspension response, frame geometry and rider position as one system.

 

The only thing that can be done with motor power is useful when there is traction.

While high motor output can assist an all terrain electric bike rise up hill, or to keep moving, more power won't make up for poor grip.

If in loose gravel or wet soil, sudden help can cause the back wheels to spin. The smoother the pedal assist delivery, the more helpful it can be as it allows the tire to have time to grip the surface without aggressive acceleration.

In assessing the drive system take account of:

la continuous motor output as opposed to the peak motor output;

lLow speed assistance response at low speed;

lavailable pedal-assist levels;

lhill-start behavior;

lLow speed climbing gear;

lTemp Management on a long ascent.

Mechanical gears have their importance even if the bike is equipped with a motor. The low gear will help to take the strain out of the drivetrain, and allow the rider to maintain cadence when riding on long gradients.

The Zoulaglide electric bike buyer's guide provides a more general overview on the selection of motor, battery, terrain, frame and features.

 

Adapting to the conditions of loose and wet surfaces when braking.

Under certain conditions of poor road grip, stopping distances can be lengthened.

Braking hard that is effective on dry pavement can cause a wheel to lock up on gravel and can cause a slide in mud. Thus, an all terrain electric bike requires a predictable braking instead of merely braking power.

Hydraulic disc brakes are capable of progressive braking, and require a relatively small effort on the handlebars. Actual stopping performance is still dependent on various factors, including rotor condition, brake-pad material, tire traction, rider weight, speed, gradient and weather conditions.

Smooth use of both brakes and weight shifting to respond to inclines are important to practice. It is better to enter an unknown corner at a controlled speed, rather than relying on emergency braking once grip has been lost.

The route determines the range in the real-world.

The range of these batteries is standard, and decreases as riding intensity increases.

The use of soft tyres, loose ground, frequent acceleration, low temperatures, strong wind, extra load and long climbs are factors that consume energy. The published test ranges should therefore be taken as figures for comparison only and not guaranteed distances.

For mixed-terrain planning:

lwork out the total distance of a return journey;

lMake sure to have a battery backup for detours and climbs;

lon easy sections use less assistance;

lCheck tires for proper inflation prior to leaving;

lDo not take the range from a single figure that represents an ideal condition.

While a removable battery may make indoor charging easier, battery location is important, too. Holding the battery in the middle will help to balance a bike while making turns or low speed climbs.

The D100's Mixed Terrain Riding Strategy.

The Zoulaglide fat-tire D100 is designed for those who regularly venture off the level roadways of urban areas and onto other surfaces.

It features a mix of a wide tyre, front shock absorption, multi-speed drivetrain, hydraulic brakes and a large capacity Samsung-cell battery system. The features fulfill various requirements of an all terrain electric bike such as floating on soft surfaces, controlling terrain on uneven surfaces, supporting uphill and downhill gradients, and providing a longer range for outdoor use.

The D100 is better for someone who doesn't care so much about transport weight as he does traction and ability to handle rough roads. In mostly paved commuting areas where there is occasional rough pavement, a smaller, lighter mixed use approach may be more efficient.

It is not the most powerful specification available that is the correct choice, but one based on terrain frequency.

 

An All Terrain Electric Bike isn't a competition Mountain Bike!

Don't assume that the terms “all terrain” and “electric mountain bike” are synonymous.

Uses of an all terrain electric bike are generally combined recreational trails, gravel roads, urban outskirts, moderate trails, sand or conditions dependent on the season. Technical mountain biking can include jumps, steep rock, sharp drops, and high impact riding which demands special frame geometry, suspension travel, wheels and certified parts.

Check manufacturer's guidance for intended use before riding. A bicycle doesn't have to look that rugged to be built for extreme downhill or for jumping.

Construct the Bike "Around the Most Difficult Place"

Most challenging section of the normal route should inform the final decision.

Consider tire flotation if it is soft sand. When it's a long climb, look at gearing, motor response, battery reserve and heat management. When descending in wet conditions, remember to control your brakes, grip your tires and adjust your riding position.

The all terrain electric bike with the most features isn't necessarily a capable machine. It is the bike that does a good job of maintaining its grip, handling, comfort and power on less predictable rides.

FAQ

Q1. All terrain electric bike – is it a thing?

An all terrain electric bike is intended for all types of surfaces like pavement, gravel, grass, light trails, mud or sand. It features a set of tires, a brake system, a driving mechanism, a suspension and an electric motor aid that all adapt to varying road surfaces.

Q2. Do fat tires really need to be used for going off-road?

Not for all routes. Gravel can be moderate, conventional wider trekking tyres work well on it, but fat-tire flotation and traction will work on sand, snow, mud and loose ground.

Q3. Are ATBs electric bikes able to tackle steep hills?

It can be used for climbing with proper matching of motor output, gearing, traction, rider weight and battery. Even with a lot of power, wet or loose gradients can still hamper grip.

Q4. Does using the vehicle off road shorten the range of the battery?

Usually, yes. A loss of grip on the road, low tire pressure, multiple ascents, higher assistance levels, and frequent acceleration all raise the amount of energy that is used versus level riding on hard pavement.

Q5. Are electric bikes for all terrain suitable for commute?

Yes definitely, particularly if you have to travel over broken surfaces, gravel cut-throughs or bad weather. But, if it's going to be all-paved, really fat tires and heavy off-road parts might not be as efficient.
