That's all it'd do. It might not even hold anything else, just crates, or maybe whatever the cargo system uses so people can scoot about being small-haul couriers with their bikes if they want to.
On the other hand, we really need more crime plots than mugging crate runners, and knocking people off their bikes and riding off into the chop shop with them is pretty freaking great, on the extremely rare times it does happen. Having people buzzing their crappy dirtbikes around doing menial chores could really open up a lot of new and exciting RP opportunities.
Yeah, I think I like this idea quite a bit, come to think of it.
While this wouldn't allow for transportation of crates of ore or 55 gallon drums of water, it would allow for the transportation of very heavy objects that need a hand cart to move. If it could be used to pack Mr. Bruce's crates onto your bike, that'd be cool too.
But as pointed out there is already a bike that can partake in the freight cargo mechanic.
I hope this isn't an overshare, but in the event you need to move things that would normally require a hand cart, you are capable of talking to the related NPC's that handle that business to arrange for delivery directly.
Even though I always advocate for supporting player enterprise and hustle, some things are simply a logistical and opsec nightmare. Some of the tools and logistical challenges make it simply a much easier thing to let a puppet handle.
Changes to car theft (while reasonable and well-intentioned) seemed to immediately and dramatically reduce GTA incidents. In previous years I've talked to a lot of PC's and experienced myself the crunch in the service mixer industries for transportation services because it has, at times, felt as if every mixer more than a few months old has a cheap bike, and every suit has a bike or a car.
People seem to overwhelmingly prefer bikes and AV's for very obvious reasons. Tube traffic mechanics can often make taking a car actually slower on average than taking a lev, which is nutty. Especially since mechanics make certain times that happen to coincide with peak MOO hours literal hell to be a car owner. Granted, car ownership has other benefits, but I don't think the costs, which can run generously into the six figure territory, outweigh the benefits of having a car.
That said, the problem could easily be addressed by more people just murdering bikers and/or stealing their shit with or without the theft skill checks. But that's a bigger cultural issue. You very, very rarely see those things happen outside very select and targeted action. So that balance mechanic that bikes are built around seems to be pretty lacking in practice, negating most of the intentional downsides of the transport system. When you take assault and aggravated theft out of the equation, owning a bike becomes a complete no-brainer move, really.
