Hi there. I'm currently planning on shoving the massive 48-volt 20AH Ping battery and 2 X GM controllers in a 20-litre Topeak bag on a Topeak rack. This isn't really an ideal setup and I would like to attach a hard top box that is lockable to the rear rack so that it is more waterproof and secure. I'll be leaving the battery pack and controllers on the bike when I park it so having them in a soft case that is easily opened and removed is not the best idea..
Can any of you recommend a good quality, lockable, hard plastic rear top box? I've seen a few in photos but not sure where I can get them. Most of the local bike shops here in Melbourne, Australia, have very limited stock of anything like that...
Cheers!
Wayne ;-)
