I am building a Vevox from Wamart kit. The rear brakes seem to only brake
one wheel which is destabilising. Is there a way to get it to brake the
other rear wheel? Am I failing to see or adjust something?

Search for 'Vevox' finds a software firm.

Walmart has a 'Vevor' tricycle with a band brake on the
drive shaft:

Since that style of tricycle has only one drive wheel
there's no practical way to brake both wheels without
extensive ($$$) reworking.

I can imagine someone cobbling a way to mount a caliper brake on the
frame member that encircles the rear wheel. But it would be a project.

Really, the front brake should be all that's needed.

The standard design for the past 50 years at least is a
solid shaft with one wheel keyed or pinned and the other
side free (which obviates differential gears). There's no
structural member outboard from the wheel, only the
occasional mudguard brace.

The other Walmart photos seemed to show a sort of horizontal hoop around
each rear wheel, perhaps just to mount the fenders. But I was guessing
maybe 1/2" OD tube, probably enough for a brake.

Yes but not suitable for a brake although plenty for a
mudguard. They bend/dent easily.

It might be easier to weld a mount for a disc caliper with a
different hub. User would need to remove axle end nut and
slide the shaft (final drive sprocket has an allen grub
screw) to change a wheel.

THanks to all the replies. Yes, Vevor.

I first an adult tricycle in 1972. June Lockhart (Lost in Space, Lassie) was
riding it in Malba NY. It was twice as large and our school bus driver went
bats. Well, I'm half sure it was her, it was near her home.
