Why double kingpin trucks change the way an electric skateboard feels

Most people shopping for an electric skateboard spend their time comparing battery capacity and top speed. The trucks barely get a mention. That is a mistake, because the geometry underneath the board determines more about how a ride actually feels than almost any other single component.

Double kingpin trucks are the reason Evolve boards carve the way they do. Understanding how they work helps explain why the Evolve riding experience feels genuinely different from boards running conventional truck geometry, and why that difference matters more in real-world riding than a few extra kilometres of range.

What makes double kingpin geometry different

A standard skateboard truck has one kingpin bolt holding the hanger in place. The bushing arrangement around that single pivot gives you a predictable lean, but the geometry limits how much turn you can generate before the truck binds or the wheel bites the deck.

Double kingpin trucks add a second pivot point. Instead of the hanger rotating around one axis, it articulates through two, which dramatically increases the steering angle available for a given amount of lean. The result is a tighter turn radius and a much more progressive carve. You lean into a corner and the board keeps responding well past the point where a standard truck would run out of travel.

For a heavy electric skateboard, this matters more than it would on a traditional push board. The extra weight of the battery and motors makes a board harder to redirect through body movement alone. Double kingpin geometry compensates for that by making the trucks more responsive, so the board turns with you rather than requiring you to force it around.

The surf carve feeling is not a marketing phrase

Evolve riders talk a lot about a surf carve feel, and it is easy to dismiss that as branding language. It is not. It describes something specific that happens when double kingpin geometry is dialled in correctly: the board follows your body weight through a turn the way a surfboard tracks through a wave face, with a progressive, connected quality rather than a sharp mechanical pivot.

That feeling comes from how the two pivot points interact under load. When you initiate a carve, the front truck begins steering first, then the rear follows and amplifies it. Done right, the board flows through the turn rather than snapping into it. The ride generates its own momentum through corners, which encourages you to link turns together rather than just pointing and going straight.

On the Gold Coast foreshore or along Brisbane's Riverwalk, where there is room to move and the path stretches ahead, that characteristic is what separates a genuinely enjoyable ride from simply getting somewhere quickly.

SuperCarve 2.0 and what the engineering actually delivers

The Diablo Bamboo runs Evolve's SuperCarve 2.0 trucks, which are forged and CNC machined rather than cast. Forging aligns the grain structure of the aluminium through the part, which produces a stronger, stiffer component from less material. CNC finishing brings the geometry tolerances down to where they need to be for the double kingpin pivots to work as designed.

The practical effect is a truck that holds its geometry under load. A cast truck can flex slightly under the weight of a heavy rider pushing hard through a corner, which introduces vagueness at the worst possible moment. A forged and machined truck does not have that problem. The board responds to your input, not to structural flex in the trucks themselves.

Bushing selection also plays a significant role. Softer bushings at 87A give more rotation and a deeper carve, which suits lighter riders or those who prefer a responsive, surf-style setup. Harder compounds at 95A and above add stability at speed and suit heavier riders or anyone who wants a more planted feel on longer, faster runs. The geometry stays the same either way; the bushings tune how quickly the truck reaches the limits of its travel.

The bamboo deck adds something the trucks cannot

Carve feel is not just about trucks. The Diablo Bamboo uses a three-ply bamboo and two-ply fibreglass layup that has a natural flex built into it. That flex works with the double kingpin geometry rather than against it.

When you load a corner, the deck absorbs some of the force and loads back up as you come through the apex, feeding energy into the exit of the turn. It is a subtle effect but a real one. Riders who have spent time on the rigid Diablo Carbon and then moved back to the Bamboo consistently describe the Bamboo as feeling more alive through corners, even if the Carbon is more planted at straight-line speed.

That combination of double kingpin geometry and bamboo flex is what makes the Diablo Bamboo feel more like a longboard than an appliance. It rewards input. It punishes laziness. That is exactly what a well-set-up deck should do.

When the geometry is at its best

Double kingpin trucks shine on any surface where you have room to work with the turning arc they generate. Wide, smooth coastal paths in Perth or Sydney's flat harbour foreshores suit them perfectly. The boards pull through long, sweeping turns with very little rider effort, and the linked-turn dynamic becomes meditative rather than demanding.

They are also genuinely capable on all-terrain setups. The Diablo Bamboo 2-in-1 ships with both 97mm street wheels and 175mm pneumatic all-terrain tyres, and the SuperCarve 2.0 geometry works well with both configurations. Swapping to all-terrain tyres raises the ride height, which changes the leverage on the trucks slightly and produces a slightly different carve character, but the fundamental responsiveness carries across. On loose gravel or compacted dirt tracks, the ability to steer actively through a corner rather than just leaning and hoping makes a real difference to confidence.

The 864Wh battery and dual 3500W motors ensure that none of that carving energy is wasted waiting for the board to catch up with the rider. Torque delivery through corners is smooth and immediate, which lets you carry speed through a turn rather than losing momentum and reaccelerating on the exit. At 14.1 kg on street wheels, the board is substantial, but the double kingpin geometry makes it feel lighter than that number suggests once you are moving.

How to get the most out of the setup

New Evolve riders sometimes tighten their trucks down looking for stability, then wonder why the board does not carve the way they expected. Trucks that are too tight prevent the double kingpin from moving through its full range of travel. The board ends up feeling wooden rather than responsive.

Start with the stock bushing setup and ride the board as it comes. Give yourself time to develop the lean and weight shift habits that the geometry rewards. Most riders find the stock configuration starts to feel natural within a few sessions. If the board feels too loose at higher speeds, move to a harder bushing compound rather than cranking the kingpin nuts down. That preserves the carve quality at lower speeds while adding the stability you want when you are moving fast.

For riders in Melbourne's inner suburbs or Brisbane's hillier routes, this tuning makes a real difference. A well-set truck gives you confidence on descents and keeps the board responsive when you need to steer actively rather than just cruise.

If you want a board that does more than move you from one place to another, the geometry underneath it matters. The Diablo Bamboo 2-in-1 is built around a truck system designed to make riding genuinely engaging, whether you are on street wheels chasing that surf carve feeling along a coastal path or on all-terrain tyres exploring something less predictable. That is what double kingpin trucks, done properly, actually deliver.
