Now bear in mind that this is an international race series and the manufacturer is also one of the larger E-bike manufacturers and know a thing or two about making e-bikes.
So making an E-bike is a nice project but getting it insured is probably not going to be that easy.
TBH There were a lot of batteries in there and the fault was suspected to come from the charging unit.
Also conventional petrol is much safer?

Remember in 2018 when the TT zero bike caught fire and set a tree on fire and they cancelled that days racing?
A homebuilt system still needs to be charged with a charger, how do you ensure that the system you have will control charging adequately?
Above 60°C the risk of thermal runaway gets very high and if that happens there better be a very good system to deal with the problem.
Conventional petrol fires can be extinguished using normal means of fire suppression.
Foam and Dry powder will both extinguish a Class B fire.
For Lithium it is much more difficult as some of the batteries release oxygen as they burn which compounds the difficulty of extinguishing the fire so you need water in large quantities.
Then you have the risk of electrocution, not insignificant with large DC systems.
My point is that battery power is not automatically benign when you are talking about the amount of contained energy that a car or bike needs to function in a manner which approximates an ICE engine.
Its still an awful lot of contained energy and has a lot of potential to go wrong and this has to be understood and managed.

to an extent, it is.
From a fire perspective you can put out a petrol fire by any one of the conventional means: starve if of fuel, starve it of oxygen, lower it's temperature. Relatively speaking in fire terms, these are known and understood, and non-specialists can put it out quite easily.
A battery otoh as mentioned by CJH has not only it's own fuel load, but the ability to 'create' it's own oxygen, and the temps are so high that huge volumes of coolant are required making them far more difficult to suppress. A much tougher cookie to crack imho.Ode To The Motorist

Btw, electric custom has been done here, just not road legal https://youtu.be/m5BUk-yINW0

Yeah the hard part is getting them road legal.. Its really a bummer, stops the maker community really thrivingBtw, electric custom has been done here, just not road legal https://youtu.be/m5BUk-yINW0

Cant see why i cant be legal...its basically an electric bicycle..are there limits to the capacity from being a bicycle to a motorcycle..... 0 -

Any mechanically propelled vechicle needs to be taxable(regardless if any tax applies) and have insurance, that includes those little electric peddle bikes and scouters.
Can't remember the exact conditions it has to meet to fall outside that requirement, basically mostly anything with a motor that doesn't depend mostly on the user generating the momentum.
Registration is so every home tutul wanna be doesn't slap together a frame and kill themselves or someone else.
I remember seeing something before where someone basically said sure Billy Lane just eyeballs things, apart from being incredibly talented in fabrication and intelligent, he was an engineer.
Him I'd trust to build a frame, John down the road who took up a new hobby..... not so much.
I'd love to build a ground up bike, but the equipment and skill required are beyond me, frame jigs, pipe benders welders, presses, adds up quick.0 -

It's not a bicycle. Under EU regs it's a PTW - Powered Two Wheeler. Aka, a vehicle.
This means Type Approval, Certificate of Conformity etc etc.
Huge task - I'm in the middle of that now for a vehicle (work), and I can tell you now that presented with a 2-wheeler, you'd be a pioneer with NSAI.... :pac::pac:Ode To The Motorist
