Spec Board Builders

Figured this place needed a quick stop reference guide to what the rules are around building a spec board, as well as a place to show off builds or purchases.

To get your own spec board you can order from stooge raceboards, look for “Moe Hawk”

or

You can build one from a meepo go, use any style truck you want, any deck, any bushings, and you’ll need 125mm mad max wheels with the 45t pulleys. Bearings have to be steel on steel. No quantum frictionless harmonic resonators allowed.
Belts should be standard.

Meepo Go Parts required.
Battery

ESC

MOTORS (14t pulley)

Remote.

Really interested to see what people come up with

Spec Guidelines we used fir for SOS, tef1, and apple valley races.

Spec Board Racing Mission statement. We are dedicated to fostering a community that emphasizes safety, learning, fun, control, and affordability. Our mission is to provide an accessible platform for riders of all skill levels to engage in exciting and competitive electric skateboard racing while prioritizing the well-being of every participant. Through ongoing education, we aim to ensure that riders not only enhance their racing skills but also learn the importance of safety and control in every ride. We believe that Spec electric skateboard racing should be fun and thrilling, without compromising on affordability, and we strive to make this dynamic sport accessible to everyone, regardless of background or experience.

Component Sourcing Statement

All required components for this Spec Class can be sourced directly through Meepo, using the Meepo Go electric skateboard as the baseline reference model. This ensures consistency, availability, and fair competition.

While individual parts may be purchased separately, all key components (ESC, battery, motors, remote, wheels, etc.) must match the specifications and models found on the Meepo Go and must comply with the individual rules outlined in this document.

  1. Wheel rule- Mad 125mm Wheel Integrity

The Mad 125mm wheel is a key component of our electric skateboard racing series, engineered for optimal performance, stability, and safety. As such, it is strictly prohibited to modify, alter, or replace any part of the Mad 125mm wheel, including its core, urethane material, or shape. This rule ensures consistent performance and maintains a level playing field for all competitors.

Any alteration to the wheel’s design, whether for aesthetic or performance purposes, can compromise its integrity, safety, and handling, potentially leading to dangerous riding conditions or unfair advantages. Riders found to have altered or tampered with their Mad 125mm wheels will be subject to penalties, including disqualification, depending on the severity of the modification.

By preserving the original design of the Mad 125mm wheel, we uphold the spirit of fairness, safety, and competitive integrity in every race.

  1. Speed Controller Rule – Meepo JKFOK-24B

The Meepo JKFOK-24B electronic speed controller (ESC) must be used in its original, unmodified form. The ESC must remain sealed within its original enclosure; removal or internal modification of the ESC or its firmware is strictly prohibited.

2 / 5

Modifications to the ESC enclosure (the outer box) are permitted solely for the purpose of safe and secure mounting to the skateboard. These modifications must not affect the internal components or performance of the ESC in any way.

Any ESC found to be tampered with, opened, or internally altered will result in disqualification

  1. Battery Rule – Meepo 12S2P 50.4V (345Wh)

The Meepo 12S2P 50.4V battery (345 watt-hour) must remain completely unaltered and enclosed in its original factory housing. The battery must retain the original manufacturer specification sticker, clearly visible and intact, for verification purposes.

The enclosure may be modified only to allow proper and secure fitment to the skateboard. Any enclosure modification must not compromise the integrity, safety, or original configuration of the battery pack or its components.

Any battery found to be internally altered, repackaged, or missing its original specification sticker will result in immediate disqualification.

  1. Remote Rule – Meepo J6

The Meepo J6 remote must be used in its stock and unaltered form. Internal modifications or hardware alterations are strictly prohibited. Cosmetic damage or wear from use is permitted.

All factory-available settings and modes may be used without restriction.

Any remote found to be internally modified or tampered with will result in disqualification.

  1. Power Wiring Rule – ESC to Battery Connection

The wiring bus connecting the ESC to the battery may be of any gauge or length, at the discretion of the builder. However, the wiring must be:

· Securely fastened to the board to prevent movement or damage during racing

· Properly insulated and protected to ensure safe operation

· Terminated with a connector that plugs directly into an XT60 on both the ESC and the battery

Adapters or custom wiring are allowed only if they meet the above safety requirements and maintain XT60 compatibility at both ends. Unsafe or improperly secured wiring may result in disqualification or required correction before racing.

  1. Motor Rule – Meepo 1500W 5040 Motors

3 / 5

Only Meepo 1500W 5040 motors are permitted. Motors must meet the following specifications:

· Stator size: 4230

· Pole pairs: 7

· Power rating: 1500 watts per motor

· Origin: Must be original Meepo-manufactured motors; no clones, rewinds, or internal modifications allowed

Motors must remain unopened and unmodified internally. Cosmetic wear and external mounting changes are allowed, provided they do not affect performance.

Any motor found to be internally altered, of a non-compliant model, or not manufactured by Meepo will result in disqualification.

  1. Belt Rule – Drive Belt Specification

All boards must use a 260-5M timing belt with a width of 15mm. The belt must be in good condition, free of fraying, missing teeth, cracks, or excessive wear that could compromise safety or performance.

Belts that do not meet the specified size or condition requirements must be replaced prior to racing. Use of non-compliant or damaged belts may result in disqualification or a mandatory repair.

  1. Gearing Rule – Pulley Specifications

All boards must use the following fixed gearing configuration:

· Wheel pulley: 45 teeth

· Motor pulley: 14 teeth

· Belt cog width: 15mm (both pulleys must match this width)

Both pulleys must be properly aligned and securely mounted. Use of alternative tooth counts, different cog widths, or modified pulley designs is strictly prohibited.

Non-compliant gearing will result in disqualification until corrected.

  1. Deck Rule – Construction and Dimensions

Decks may be of any material, construction, length, width, or drop height. There are no restrictions on flex, concave, shape, or mounting style (e.g., top-mount, drop-through, double drop).

Deck modifications for mounting components, wire routing, or rider comfort are permitted, provided they do not compromise safety or structural integrity.

All decks must be free of major cracks, damage, or defects that could pose a safety risk.

4 / 5

Steering Rule – Trucks and Setup

Any steering system or truck type is allowed, including reverse kingpin, traditional kingpin, channel trucks, or other designs. There are no restrictions on:

· Truck width or height

· Bushing type, shape, or durometer

· Pivot cups, washers, or dampers

· Mounting angles or riser configurations

All steering setups must be securely mounted and must pass safety inspection, showing no signs of failure risk (e.g., cracked baseplates, bent axles, or loose components).

Unsafe or unstable steering setups may be disqualified or required to be corrected before racing.

  1. Bearing Rule – Steel-on-Steel Only

All wheel bearings must be steel-on-steel construction — that is, both the balls and races must be made of steel.

Ceramic bearings, hybrid bearings, or any bearings using ceramic components are not allowed.

Bearings must be in good working condition, securely seated in the wheels, and free of excessive wear or damage.

  1. Rider Safety Rule – Required and Recommended Protective Gear

Mandatory Gear (Required to Race):

All riders must wear the following protective gear during practice and racing:

· A full-face helmet with a minimum DOT safety rating (ECE, Snell, or FIM also accepted).

o Skate-style helmets are strictly prohibited.

· A spine protector, either standalone or integrated into a protective suit/jacket

· Knee and elbow protection, using hard-shell or impact-rated pads

· Close-toed shoes in good condition (no sandals or barefoot riding)

All gear must be securely fitted, undamaged, and approved at safety inspection. Riders without required gear will not be allowed on the track.


Recommended Gear (Strongly Encouraged):

For additional safety, the following gear is highly recommended:

5 / 5

· Full-body protective suit (leather or textile with built-in armor)

· Wrist guards or protective gloves with wrist support

· Hip pads or padded shorts

Looks pretty good, even though I would prefer to see people racing on solid rubber which provides much more predictable sliding over urethane which has more knife edge grip.

I would like to see the option of other belt lengths, because if your intention is to allow people to race different chassis’ then a fixed belt length rules out many truck systems which have existing motor mounts and not all boards have clearance for forward facing motors which often means longer mounts and belts with traditional truck geometry.

It’d be cool to be able to race the Mach One chassis just by throwing the Meepo electronics into it and everything would be compliant except that the belts would be 375mm length.

Loosening up the belt length rule is a goid idea.

Not Purely for safety I think opening up wheel options to radiums would mean heavier riders aren’t at as much of a disadvantage. The Mad Wheels make weigh classes required for spec. The grip falls off a cliff for heavier riders.

I think radiums are just an all around better wheel than mad 125s. I’d love to see a radium wheel spec class.

But also I think weight classes are 100% needed as long as everyone has the same power, especially since the power level is so low. I am personally really not a fan of giving lightweight and heavy riders the same power to see who is faster.

Why not just mandate a ballast to standardize overall rider + board weight?

Would you want to race on a board with 30kg ballast, or wear a 30kg backpack for a race? It’d make handling worse and very unfamiliar for lighter riders

Because you have riders that weigh 50kg and others that are close to 100kg. Can you imagine a guy like Dylan wearing 50kg ballast? :joy:

@MoeStooge how many sets of wheels would you need to run this?

I have two spec boards with them.

We put all boards in impound. They do not get recharged as they are cycled through different racers hotlaps heat races and mains.

Main factor would be watt hr per mile loss. What is the watt hr per mile usage on your wheel?

Would be intersting to run side by side with the mad125. I suspect while there would be lateral grip gains, top speed would be down. Would be a fun trade-off pay out.

Yeah the SR125’s will definitely suck more battery, but the Mad 125’s weren’t as efficient as I expected when I tried them so I think best way to find out is just try it. We’ll send you guys a set for testing if you want. If it works out well we’re open to sponsoring a whole bunch of wheels.

I’ll send you a dm.

I wanna see a spec race geared towards efficiency.

Only rules are a makerx vesc4 (or some other standard) and 50 p42a cells.

Everything else is open

But that’s my nerdy builder take

Im sure we could talk @AP-E-Sk8 into doing a watthr consumpion and performance evaluation.

Dont threaten me with a good time
