The Carryish Take
Bottom line: A well-built pet taxi for families who prioritize furry passenger comfort over e-bike performance value.
Best for
- Multi-dog families who want all pets included on outings
- Pet parents with mobility issues who need stable loading
- Flat-terrain riders with garages big enough for a small car
- Dog daycare operators doing neighborhood pickups
Not for
- Hilly terrain riders — that 45Nm motor will disappoint
- Budget buyers — a Tern GSD S00 costs less and does more
- Small living spaces — this takes up serious real estate
- Single-dog owners who could use a regular longtail
Pros & Cons
What we like
- +600-lb total capacity handles multiple large dogs plus cargo
- +Three-wheel stability means no balancing with squirmy passengers
- +Pet-specific front box with ventilation and secure harness points
- +614Wh battery provides 25-35 miles with heavy loads
- +Dual-leg kickstand keeps the trike stable during loading
Watch out for
- –At 168 lbs, it's heavier than most compact cars' spare tires
- –$6,999 price tag for relatively basic 500W hub motor tech
- –45Nm torque struggles on hills with multiple large dogs aboard
- –Massive footprint makes storage a real challenge
- –Class 1 speed limit feels slow when you're hauling this much weight

Frequently Asked Questions
How many dogs can it actually carry?
Four medium dogs (40-50 lbs each) or two large dogs up to 80 lbs. The front box measures 36" x 24" x 20" deep.
Does it work for nervous dogs?
The low loading height and stable three-wheel design help anxious pets. You'll still need training time, but it's easier than a regular bike.
Can I use it without pets?
Absolutely — that 600-lb capacity handles massive grocery runs or gear hauling. Just remove the pet barriers and you have a cargo trike.
How does it handle in traffic?
The wide stance (about 32") means you can't lane-split, but the upright position gives great visibility. Stick to bike lanes or quiet streets.
Against the Urban Arrow Family ($4,500), you get pet-specific features but pay $2,500 more for less sophisticated tech. The Lectric XP Trike ($1,999) hauls pets too, but without the custom compartment or capacity.
