Oooo.... Just as I'm getting ready to order a new Pashley Pronto Go.
@2_Wheeled_Wolf This is a very "logical" design. I wish I could have mounted the battery like that on the elephant bike
@jfparis you can, I did similar on the old Mailstar I'm using atm. I custom build a hardwood platform to fix battery onto.

@2_Wheeled_Wolf Well you are losing the rack with that hack.

That the only improvement on their new factory model

@jfparis I don't use the rack anyway, just there to carry my huge Ortlieb panniers & battery. Other additions now available are dynohub powered front light & since 2025 you can now upgrade to an 8 speed Nexus hub on the Pronto & Pronto Go.
@2_Wheeled_Wolf
For us it was important to put the child seat
@jfparis that makes sense, perhaps the Pronto Go rear rack could fit on the Elephant bike's frame & change the battery.
