Article 301.08 · 2026 edition
Electric Challenge
An open class: the rulebook names no manufacturer, and Art. 505 sets no production minimum either. The technical regime is a set of measurable limits rather than a list of permissions.
Who may enter Electric Challenge: age, gender and licence
- Age
- 16 years and over, counted "within the relevant calendar year" as Art. 301.08 puts it.
- Gender
- Open to male and female riders.
- Minimum field
- 5 riders. Below that, the class is cancelled for that race (Art. 301.08).
- Same weekend
- Art. 301 limits a rider to one class per racing weekend and makes Electric Challenge the exception, so it can be entered alongside another class.
- Licence
- An International licence from the rider's National Authority is compulsory across the championship. Applying for one, through a club, is covered on the how to start MotoSurf racing page.
* Stock Men: does not take the previous season's Stock Men champion, who moves up to Elite Men unless the MotoSurf Committee decides otherwise (Art. 301.03), nor, unless the Motosurf Committee grants an exception, an Elite Men rider under 40 who finished in last season's top 8 or has raced two or more Elite Men rounds this season (Art. 301.01).
* Elite Men: takes a rider only after a completed Stock Men race in the season before, unless the Motosurf Committee grants an exception, and keeps for the rest of the season a rider who has raced two or more of its rounds (Art. 301.01).
Where bars in one group overlap, a rider of that age fits more than one band. Every band counts the age reached during the calendar year, and under Art. 301.09 the Motosurf Committee may still move a rider to another class.
How we know: Each bar is a class record's age band and rider, from the 2026 MotoSurf Rulebook, Art. 301.01 to 301.08.
Which boards the rulebook names for Electric Challenge
No board is named, and no minimum production run is required. A board in this class is held to the limits and requirements of Art. 505 set out below.
Technical limits, Article 505
This article covers Electric Challenge and no other class.
- Power
- No motor power figure, no battery capacity, no cell chemistry and no charger output rating appear anywhere. The electric rule is a voltage cap and a pack count.
- Board length
- 200 cm maximum
- Board width
- 80 cm maximum. No other class has a board width limit. The 2025 edition set the same 80 cm for Electric Challenge and none for anything else.
- Mass
- 45 kg maximum, including the battery pack
- Battery
- 60 V maximum when fully charged. 3 labelled packs per board for the whole event.
- Main fin
- 230 mm maximum height, 340 mm maximum length
- Maximum voltage of fully charged battery must not exceed 60 V.
- Maximum mass of the board including battery pack must not exceed 45 kg.
Art. 505.
Other requirements in this article
- Maximum three labelled battery packs per board for the duration of the entire event.
- Each charger must be CE certified. The rulebook's sentence about the household outlet it must charge from appears to have lost a figure in publication, so no amperage is recorded here.
- Battery packs must report voltage and current over CAN BUS 2.0 at 500 kB. The connector type is printed in the rulebook as a placeholder and the critical temperature, humidity and pressure values are delegated rather than stated.
- A wireless throttle controller must shut off the motor immediately after being dropped from the rider's control.
A second document for this class
A separate technical document governs this class too: the UIM MotoSurf Electric Rules 2025. It carries detail Article 505 leaves out: cell configuration, charging cut offs and a manufacturer homologation fee. The two disagree on the battery telemetry. Art. 505.03 c) gives it as Big Endian, and the electric rules give Little Endian with different CAN identifiers. This site records both and stores neither as the specification. Both documents are listed on the sources page.
Fin rules for Electric Challenge
Only officially certified FCS fins are allowed.
Art. 505.04 (Fins requirements) d)
What the rulebook publishes on fin geometry is on the MotoSurf fin rules page.
Safety gear for Electric Challenge in the safety articles (4)
- Helmet Art. 507.01 a)
- Life jacket Art. 507.01 c) and 507.02 c)
- Neck brace Art. 507.01 d) and 507.02 d)
- Leash Art. 507.01 e) and 507.02 e)
What each item must meet, and the kit required elsewhere, such as the environmental mat, is on the MotoSurf racing gear page.
Race format: laps in Electric Challenge
Under Art. 307, Electric Challenge heats run 5 laps, 2 long, and the final, printed as F1, runs 6 laps, 2 long. Race Direction may change the long laps if riders are told at the briefing or by bulletin, so these are a starting point, not a schedule.
The course, the starts and how points are scored are on the MotoSurf race format page.
Title holders named in the rulebooks
- Yano Vankersbilck, Belgium, printed on the 2026 cover as champion of the Electric Challenge.
- Lukáš Záhorský, Czechia, printed on the 2025 cover as champion of the Electric Challenge.
Every season's champions, under the promoter's own class names, are on the MotoSurf champions page.
What changed since the 2025 edition
The 2025 edition ran both an F1 and an F2 final for this class. 2026 runs an F1 only.
