ISO 4210:2014 Bikes

The ISO standard uses different “Condition” classifications to indicate what a particular bike has been built for and hence what you can expect from it. The following list details each recognised condition and its pros and cons.

High-Performance Road CONDITION 1

Bikes designed for riding on a paved surface where the tyres do not lose ground contact.

INTENDED To be ridden on paved roads only.

NOT INTENDED For off-road, cyclocross, or touring with racks or panniers.

TRADE OFF Material use is optimised to deliver both light weight and specific performance. You must understand that (1) these types of bikes are intended to give an aggressive racer or competitive cyclist a performance advantage over a relatively short product life, (2) a less aggressive rider will enjoy longer frame life, (3) you are choosing lightweight (shorter frame life) over more frame weight and a longer frame life, (4) you are choosing light weight over more dent resistant or rugged frames that weigh more. All frames that are very light need frequent inspection. These frames are likely to be damaged or broken in a crash. They are not designed to take abuse or be a rugged workhorse.

MAXIMUM WEIGHT LIMIT

ISO mark = Road: Maximum permissible total weight limit of rider, bicycle and luggage = 135kg

ISO mark = Young Adult: Maximum permissible total weight limit of rider, bicycle and luggage = 95kg

General Purpose Riding CONDITION 2

Bikes designed for riding Condition 1, plus smooth gravel roads and improved trails with moderate grades where the tyres do not lose ground contact.

INTENDED For paved roads, gravel or dirt roads that are in good condition, and bike paths.

NOT INTENDED For off-road or mountain bike use, or for any kind of jumping.

Some of these bikes have suspension features, but these features are designed to add comfort, not off-road capability. Some come with relatively wide tyres that are well suited to gravel or dirt paths. Some come with relatively narrow tyres that are best suited to faster riding on pavement. If you ride on gravel or dirt paths, carry heavier loads or want more tyre durability talk to your dealer about wider tyres.

MAXIMUM WEIGHT LIMIT

ISO mark = City & Trekking - Maximum permissible total weight limit of rider, bicycle and luggage = 135kg*

ISO mark = Young Adult bicycles - Maximum permissible total weight limit of rider, bicycle and luggage = 95kg

ISO mark = Road: Maximum permissible total weight limit of rider, bicycle and luggage = 135kg *

Except Folding bicycles - Maximum permissible total weight limit of rider, bicycle and luggage = 105kg

Cross-Country, Marathon, Hardtails CONDITION 3

Bikes designed for riding Conditions 1 and 2, plus rough trails, small obstacles, and smooth technical areas, including areas where momentary loss of tyre contact with the ground may occur. NOT jumping. All mountain bikes without rear suspension are Condition 3, and so are some lightweight rear suspension models.

INTENDED For cross-country riding and racing which ranges from mild to aggressive over intermediate terrain (e.g., hilly with small obstacles like roots, rocks, loose surfaces and hard pack and depressions). Cross-country and marathon equipment (tyres, shocks, frames, drive trains) are light-weight, favouring nimble speed over brute force. Suspension travel is relatively short since the bike is intended to move quickly on the ground.

NOT INTENDED For Hardcore Freeriding, Extreme Downhill, Dirt Jumping, Slopestyle, or very aggressive or extreme riding. Not intended for spending time in the air, landing hard and hammering through obstacles.

TRADE OFF Cross-Country bikes are lighter, faster to ride uphill, and more nimble than All-Mountain bikes. Cross-Country and Marathon bikes trade off some ruggedness for pedalling efficiency and uphill speed.

MAXIMUM WEIGHT LIMIT

ISO mark = Mountain bike - Maximum permissible total weight limit of rider, bicycle and luggage = 135kg

ISO mark = Young Adult bicycles - Maximum permissible total weight limit of rider, bicycle and luggage = 95kg

All Mountain CONDITION 4

Bikes designed for riding Conditions 1, 2, and 3, plus rough technical areas, moderately sized obstacles, and small jumps.

INTENDED For trail and uphill riding. All-Mountain bicycles are: (1) more heavy duty than cross country bikes, but less heavy duty than Freeride bikes, (2) lighter and more nimble than Freeride bikes, (3) heavier and have more suspension travel than a cross country bike, allowing them to be ridden in more difficult terrain, over larger obstacles and moderate jumps, (4) intermediate in suspension travel and use components that fit the intermediate intended use, (5) cover a fairly wide range of intended use, and within this range are models that are more or less heavy duty. Talk to your retailer about your needs and these models.

NOT INTENDED For use in extreme forms of jumping/riding such as hardcore mountain, Freeriding, Downhill, North Shore, Dirt Jumping, Hucking etc. No large drop offs, jumps or launches (wooden structures, dirt embankments) requiring long suspension travel or heavy duty components; and no spending time in the air landing hard and hammering through obstacles.

TRADE OFF All-Mountain bikes are more rugged than cross country bikes, for riding more difficult terrain. All-Mountain bikes are heavier and harder to ride uphill than cross country bikes. All-Mountain bikes are lighter, more nimble and easier to ride uphill than Freeride bikes. All-Mountain bikes are not as rugged as Freeride bikes and must not be used for more extreme riding and terrain.

MAXIMUM WEIGHT LIMIT

ISO mark = Mountain bike - Maximum permissible total weight limit of rider, bicycle and luggage = 135kg

ISO mark = Young Adult bicycles - Maximum permissible total weight limit of rider, bicycle and luggage = 95kg

Gravity, Freeride, and Downhill CONDITION 5

Bikes designed for jumping, hucking, high speeds, or aggressive riding on rougher surfaces, or landing on flat surfaces. However, this type of riding is extremely hazardous and puts unpredictable forces on a bicycle which may overload the frame, fork, or parts. If you choose to ride in Condition 5 terrain, you should take appropriate safety precautions such as more frequent bike inspections and replacement of equipment. You should also wear comprehensive safety equipment such as a full-face helmet, pads, and body armour.

INTENDED For riding that includes the most difficult terrain that only very skilled riders should attempt. Gravity, Freeride, and Downhill are terms which describe hardcore mountain, north shore, slopestyle. This is “extreme” riding and the terms describing it are constantly evolving. Gravity, Freeride, and Downhill bikes are: (1) heavier and have more suspension travel than All-Mountain bikes, allowing them to be ridden in more difficult terrain, over larger obstacles and larger jumps, (2) the longest in suspension travel and use components that fit heavy duty intended use. While all that is true, there is no guarantee that extreme riding will not break a Freeride bike. The terrain and type of riding that Freeride bikes are designed for is inherently dangerous. Appropriate equipment, such as a Freeride bike, does not change this reality. In this kind of riding, bad judgment, bad luck, or riding beyond your capabilities can easily result in an accident, where you could be seriously injured, paralysed or killed.

NOT INTENDED To be an excuse to try anything. Read Section 2. F, p. 13.

TRADE OFF Freeride bikes are more rugged than All-Mountain bikes, for riding more difficult terrain. Freeride bikes are heavier and harder to ride uphill than All-Mountain bikes.

MAXIMUM WEIGHT LIMIT

ISO mark = Mountain bike - Maximum permissible total weight limit of rider, bicycle and luggage = 135kg

ISO mark = Young Adult bicycles - Maximum permissible total weight limit of rider, bicycle and luggage = 95kg

 

Dirt Jump CONDITION 5

Bikes designed for jumping, hucking, high speeds, or aggressive riding on rougher surfaces, or landing on flat surfaces. However, this type of riding is extremely hazardous and puts unpredictable forces on a bicycle which may overload the frame, fork, or parts. If you choose to ride in Condition 5 terrain, you should take appropriate safety precautions such as more frequent bike inspections and replacement of equipment. You should also wear comprehensive safety equipment such as a full-face helmet, pads, and body armour.

INTENDED For man-made dirt jumps, ramps, skate parks other predictable obstacles and terrain where riders need and use skill and bike control, rather than suspension. Dirt Jumping bikes are used much like heavy duty BMX bikes. A Dirt Jumping bike does not give you skills to jump. Read Section 2. F, p. 13.

NOT INTENDED For terrain, drop offs or landings where large amounts of suspension travel are needed to help absorb the shock of landing and help maintain control.

TRADE OFF Dirt Jumping bikes are lighter and more nimble than Freeride bikes, but they have no rear suspension and the suspension travel in the front is much shorter.

MAXIMUM WEIGHT LIMIT

ISO mark = Mountain bike - Maximum permissible total weight limit of rider, bicycle and luggage = 135kg

ISO mark = Young Adult bicycles - Maximum permissible total weight limit of rider, bicycle and luggage = 95kg

 

Cyclo-cross CONDITION 2

Bikes designed for riding Condition 1, plus smooth gravel roads and improved trails with moderate grades where the tyres do not lose ground contact.

INTENDED For cyclo-cross riding, training and racing. Cyclo-cross involves riding on a variety of terrain and surfaces including dirt or mud surfaces. Cyclo-cross bikes also work well for all weather rough road riding and commuting.

NOT INTENDED For off road or mountain bike use, or jumping. Cyclo-cross riders and racers dismount before reaching an obstacle, carry their bike over the obstacle and then remount. Cyclo-cross bikes are not intended for mountain bike use. The relatively large road bike size wheels are faster than the smaller mountain bike wheels, but not as strong.

MAXIMUM WEIGHT LIMIT

ISO mark = Road: Maximum permissible total weight limit of rider, bicycle and luggage = 135kg

ISO mark = Young Adult: Maximum permissible total weight limit of rider, bicycle and luggage = 95kg

 

Road Tandems CONDITION 1

Bikes designed for riding on a paved surface where the tyres do not lose ground contact.

INTENDED Are designed to be ridden on paved roads only. They are not designed for mountain biking or off-road use.

NOT INTENDED Road tandem should not be taken off-road or used as a mountain tandem. MAXIMUM WEIGHT LIMIT Maximum permissible total weight limit of rider, bicycle and luggage = 230kg

 

Mountain Tandems CONDITION 2

Bikes designed for riding Condition 1, plus smooth gravel roads and improved trails with moderate grades where the tyres do not lose ground contact.

INTENDED The challenges of mountain biking are obvious. The added challenges of tandem riding mean that you should limit off-road tandem riding to easy-moderate terrain.

NOT INTENDED For very aggressive mountain bike riding. Mountain tandems are most definitely NOT for Downhill, Freeriding, North Shore. Choose terrain with the abilities of both the Tandem’s captain and stoker in mind.

MAXIMUM WEIGHT LIMIT Maximum permissible total weight limit of rider, bicycle and luggage = 230kg

Kids CONDITION 6

Bikes designed to be ridden by children. Parental supervision is required at all times. Avoid areas involving motorised traffic, obstacles or hazards including inclines, curbs, stairs, sewer grates or areas near drop-offs or pools.

Bikes labelled with the Young Children standard ISO8098 should not be used on the public highway.

MAXIMUM WEIGHT LIMIT

ISO mark = City & Trekking - Maximum permissible total weight limit of rider, bicycle and luggage = 95kg

ISO mark = Young Adult bicycles - Maximum permissible total weight limit of rider, bicycle and luggage = 95kg

ISO mark = Young Children - Maximum permissible total weight limit of rider, bicycle and luggage = 60kg
