Racing eMTBs: Taking On A Special Challenge

It sounds like the European EMTB racing authorities have taken immediate action to prevent motor brands having too much power. The new regulations for the upcoming EMTB World Championships are Max Speed 25kph, Cont Power 250wh, Max Peak Power 750wh which then excludes Dji/Avinox motors. Plus a max weight for batteries. Scroll through to 7:27 mins in and they chat about it here:

Ras, I don't want to watch it. Please tell me what the max weight of the batteries is. Thank you in advance!
 
Can't remember or I would have quoted it!! It was not high, another method of standardising different bikes.
As you know, I participate in gravel e-races, and when there is a larger group of e-bikers in the race (this time, six of us) I rather ride for fun as I ride a legal e-bike (acc to the Rules) but my battery capacity is a way lower than a rider with a, say, 750 Wh battery.

The organizer (who is an e-biker at times himself) does not understand the battery capacity should be capped (at, say, 800 Wh) so I could use my numerous Range Extenders. He says "A single battery set". IMHO, it should be the racers to set the rules, and the org should listen to them. Now, we have 94 km and 550 m elevation gain. How can I compete against a 750 Wh racer with my (degraded) 450 Wh main battery + RE?

😆 😆 😆 😆 😆 😆

If the racers were to set the rules, there would be no rules.

IMO there should be no battery capacity limits. There are way too many variables. It should be up to the rider to calculate what they need and plan accordingly. If the 750Wh battery rider doesn't have to stop, and the 450Wh battery rider does to change range extenders, that's racing. It's no different than the guy on the analog bike in a road race choosing too small a cassette for a major climb, or a cyclocross rider choosing to set their air pressure too low. Choices.
 
If I were allowed to take 750 Wh, I would take the main battery and 3 range extenders. Currently, these degrades batteries hold 720 Wh.
However, the org sticks to the sick idea the rider cannot take more than the factory had installed on the e-bike.

So I went back and had a look. That World Championship Enduro race was 70km with 7000m of climbing. The Battery size limit was actually a weight limit of 4.5kg.

These are UCI regulations so perhaps you can check if the UCI has any regs or even guidelines for e gravel races yet? At the moment it seems to be at a 'fun' level like Stefan's racing in Poland with any and all e bikes allowed as there just aren't enough specific e gravel bikes in the way that there are with EMTBs.

I do agree. The e-bikes on my race can be anything. Like a city Winora e-bike (750 Wh) or a Decathlon e-MTB, or a Trek Fuel EXe or whatever. I intend to talk with any of my competitors and take photos of their e-bikes. My only strength on that race is my big experience but certainly not strong legs :) It will be my 7th e-bike gravel race!
