Without that counterweight, there would be very little weight on the
front wheels.

How, out of interest, does that differ from a normal rear-engined bus?

The batteries are several tonnes heavier than an engine+fuel tank.

The 12m BYD/ADL Enviro 200EV's GVW is 18,600kg.
The near-equivalent 11.8m Enviro 200 diesel bus is 14,400kg.

Probably the bulk of the extra weight is batteries.

There are two other electric buses that were tried briefly on the Red Arrow routes and are now being transferred to route 108. These are Irizar i2e's which appear to have all the batteries in a full-length roof pod. They thus appear to be rather taller than normal single-deck buses, and have similarities to the hydrogen buses on route RV1.

Whereas the original BYDs had a pronounced but not unpleasant whine from the electric motors, the newer ones are quieter but the Irizars were very quiet indeed - an impressively smooth ride.
