Comparison Crisp Scooters Ultima vs Crisp Scooters Inception

The material of the handlebar carries almost the main information about the strength of the scooter since the rider leans on it while riding. Accordingly, this structural element in most cases is made of metal, namely:

— Aluminium. The key advantage of aluminium is its light weight. Handlebars made of aluminium are much lighter than their steel counterparts. A scooter with an aluminium handlebar can be a good choice for stunt riding. But to make an aluminium handlebar strong enough manufacturers have to increase the size and wall thickness. As a rule, aluminium handlebars have a non-standard increased tube size of 34.9 mm. Additionally, aluminium handlebars are more expensive than steel counterparts.

— Steel. The main advantage of steel is increased strength — such a handlebar can easily withstand high mechanical loads. But among the shortcomings can be noted high weight. Steel wheels have a high mass, which somewhat limits their scope, especially in terms of stunt driving.

The weight of the scooter, its strength and resistance to stress depend on the material of the deck. In modern models, the following options can be used:

— Plastic. In scooters, this material belongs to the entry-level. The strength of plastic is low, it is not designed for heavy weight and serious loads — and, therefore, it is found mainly in models of the younger age group and the classic type (see above). On the other hand, in this category, plastic shows itself at its best: it can have almost any colour and pattern, it weighs a little, and it is inexpensive.

— Aluminium. Aluminium-based alloys combine strength, resistance to stress and low weight, due to which they are quite popular as a material among all types of scooters (see above).

— Steel. The main advantage of steel is its high strength, exceeding even aluminium, not to mention plastic. On the other hand, this material has a large weight and therefore is used less often than others, mainly in bicycle scooters (see "Type") of the older age group.

— Magnesium alloy. A fairly advanced material that combines very low weight with high strength and elasticity. At the same time, its cost is also quite high. Therefore, magnesium frames can be found mainly in expensive premium models.

— Carbon. Thi...s term usually refers to carbon fibre — carbon fibre in combination with a polymer filler. Carbon is considered a premium material: its strength is comparable to steel, and its weight is much less. However, such material is sensitive to point impacts — cracks may appear from them. However, in general, such a “trouble” requires a rather unfortunate set of circumstances. But one of the unequivocal disadvantages of carbon can be called a high cost. In addition, we note that this material is used mainly in electric scooters (see "Type") — for other varieties, for several reasons, it is easier to use more affordable materials, even if we are talking about an expensive and high-quality model.

— 2 bolts. 2-bolt clamp — such clamps are typical for entry-class scooters. A 2-bolt clamp usually connects steering elements in city scooters. M8 threaded fasteners are most often used as bolts. The 2-bolt connection is ill-suited to resist loose fasteners.

— 3 bolts. Clamp for 3 bolts — this clamp allows you to more or less securely fix the steering elements. Scooters with a 3-bolt clamp are usually considered stunt scooters but belong to the entry-level class. The 3-bolt fastening allows the clamp to prevent loosening in the connection.

— 4 bolts. 4 bolt clamp — this category of clamps is typical for good stunt scooters. Such a connection allows you to securely fix the steering elements. The presence of 4 fixation points allows the connection to resist loosening well, and the bolts in such clamps are slightly subject to self-loosening.

— 5 bolts. The 5-bolt clamp is a quality clamping solution found on advanced stunt scooters. The presence of 5 fixation points allows you to securely fix the steering wheel in the desired position. The 5-bolt clamp will not allow play to appear in the connection. Such clamps can maintain the degree of tightening of fasteners even under high-vibration loads.

Compression is a special device that connects the fork to the steering speaker. Thanks to the compression, the rigidity and reliability of the connection of the steering speaker to the fork are ensured.

— IHC. Suitable for scooters with standard diameter handlebars: 31.8mm or 1¼". This type of compression is simple in design and highly reliable. The IHC system consists of a tie bolt and an anchor. The steering wheel is connected to the compression with a clamp.

— HIC(Hidden Compression System) — this type of compression is found in scooters with a handlebar of increased diameter: 34.9 mm or 1⅜". HIC compression is widely used due to the reliability and simplicity of the design solution. The steering speaker is used with a kerf Steering clamp is applied to the steering speaker HIC compression is identical to the IHC design The only difference between the two is the rudder diameter HIC is designed for 34.9mm headsets while IHC applies to headsets 31.8 mm in diameter.

— SCS(Standart Compression System) — advanced class compression. To use the SCS, you need a scooter with a non-kerf steering speaker. A distinctive feature of the SCS compression is the use of a 4-bolt tie-down collar. The compression pinch bolt is screwed in from top to bottom. The steering speaker is put on from above. SCS compression is created under the handlebars of di...fferent diameters: 34.9 or 31.8 mm. Structurally, SCS compression is similar to HIC. The key difference between these types of compression is for the most part only in the cut on the steering speaker. The SCS does not have a kerf, but the HIC does.

— ICS(Inverted Compression System) — simple and reliable compression. The system is represented by a coupling bolt, which is screwed in from the bottom up, through the front wheels. The anchor is usually built into the fork at the factory. But in some cases, the anchor must be hammered into the fork yourself. When working with compression, there are usually several difficulties. The first is that you need a special long key to work with fasteners. The second trick is expressed in the need to remove the front wheels every time the compression is tightened.

— Tread. Threading is the simplest method of connecting a steering speaker to a fork. This type of compression is typical for entry-level scooters. Scooters with threaded compression are positioned as urban models. Such scooters are not physically adapted to the impact of high mechanical loads.

The diameter of the front wheel(s) of the scooter.

This parameter is selected by the manufacturer depending on the type, age category and general purpose of the scooter. If we compare similar models with different wheel diameters, then it is worth considering that the larger the wheels, the better they work on the bumps in the road, and the higher the cross-country ability. And small wheels, in turn, are great for smooth asphalt and dynamic driving, they easily accelerate and allow you to make sharp turns.

The diameter of the rear wheel(s) of the scooter. See "Front wheel diameter" for details on the value of this parameter.

The rigidity of the wheels supplied in the scooter

The higher the number given in this parameter, the harder materials are used in the design of the wheels and the stiffer they are. Stiff wheels easier roll on different surfaces, it is easier to accelerate on them, they allow you to more accurately feel the surface under your feet and do not wear out as quickly as soft ones; on the other hand, these wheels have less traction, are more prone to vibrations and bumps, and require extra care when cornering. Therefore, wheels with high rigidity are typical mainly for professional models, and soft options are recommended for beginner riders.

Note that most scooters allow wheel replacement; this procedure is mandatory from time to time since the wheels tend to wear out. However, if necessary, you can also change a kit that is quite suitable for riding — to a harder one, or vice versa, a softer one

— 82A. Wheels with a hardness of 82A are optimal for urban scooters. This level of stiffness provides the wheels with good strength, while the wheels tenaciously contact the rolling surface. Such scooters are poorly suited for stunt riding.

— 84A. Wheels with a hardness of 84A are considered universal. These can be found both in city scooters and models for stunt riding. Rigidity at the level of 84A gives the wheels a good level of strength. Such scooters are still able to "softly" contact with the surface of the roll, but the rider will al...ready feel "hard feedback" when hitting bumps.

— 85A Wheels with a hardness of 85A are more related to stunt scooters. This level of rigidity provides the wheels with a good level of strength, but due to the increased rigidity, the soft contact of the wheels with the rolling surface is lost. If the scooter does not have suspension, the stiffness of the wheels will recoil into the platform and steering rack when hitting bumps.

— 86A. Wheels with a hardness of 86A are used in scooters for sports and stunt riding. Rigidity at the level of 86A is considered increased. Scooters with such wheels are usually designed for fairly high loads. Such wheels transmit impact and vibration to the scooter. Scooters without their shock absorption make riding on such hard wheels less comfortable. But at the same time, as the strength characteristics of the wheels increase, the chassis becomes more reliable and durable.

— 88A. Wheels with a hardness of 88A are found in stunt scooters. They are distinguished by increased strength characteristics. Due to the high rigidity of the wheels, they can easily withstand driving on any type of rolling surface. On the other hand, riding on 88A wheels provides very strong feedback to the platform and steering column. Such wheels are recommended for scooters with a built-in shock absorption system.

The maximum height to which the height-adjustable handlebar can be set (or just the height of the handlebar in the working position, if height adjustment is not provided).

The height of the handlebars should be such that the rider can stand on the deck straight, without bending his back, and hold on to the handles with slightly bent arms. At the same time, there is no unambiguous relationship between this parameter and the height of the rider. So the perfect option to determine the optimal height is to try it yourself, and then choose a scooter based on the result.

Scooter deck size. This item can indicate both the length and width or only one size — most often this is the length.

In general, this parameter is secondary: manufacturers choose the size of the deck depending on the type, age category, general specialization and other features of the scooter. Legroom, usually, is guaranteed to be enough on the deck. We only note that shorter decks are more agile, and longer ones are stable on the course.
