what is the advantage of 3 wheels verse 4
1111331
I love the 3 wheel since it makes turning much easier. The wheels are also hard rubber and not plastic which adds to the ease. I have found with four wheels that any unevenness in the ground or nicks on the wheels prevents them from turning in tandem and one is constantly stopping to line them up.

I don't know about it being an advantage, but three wheels is less bulky than four; therefore making it more lightweight and easier to push and maneuver.

the 3 wheel does better on rough terrain, also the more wheels you have the more problems you have with one breaking or turning the wrong way.

The load is much more stable and puts far less tongue weight on the four wheeler. Much safer.

The A3 has larger wheels for more stability. You can tell they're bigger, but it's not such a difference that, say, a kid would get picked on for having a babyish scooter.

You always can adapt board (size product) with 4 wheels including 2 with breaking system

This combo is kinda a dog on 2s, 3s is perfect. But 4s it's a monster. I run my combo in my vxl on 3s all day and it's a blast. Tons of power wheelies on command. Dosnt get hot even on high gearing. Hope this helps

The four wheels are stronger, however, you can make tighter turns with the three, not as stable. I recommend the 4 wheeler, especially for my next cart...

I don't have the 3-wheel...but I have used every type of 3-wheel made....with kids and pets. The 4 wheel is far more stable. When you roll on sidewalks and come to the corner, the sidewalk slants in our area. The 3 wheel feels like it will tip. The 4 wheel feels stable.

It's pretty stable. It's just not as stable as 4-wheels for obvious reasons. I love my 3-wheeled walker. Lighter, easier to fold and handles better & it will go through smaller openings.

The larger wheels allow the rider to go on grass, gravel anywhere they want to go, if they have small wheels, pavement or sidewalk are all they can do. I hope this helps, my granddaughters love theirs, they get a lot of use.

it seems b-agile 3 has four wheels while this one have three wheels. Also, b-agile 3 has three fold of the sun cover, while this one has two fold.

There were two sets of two wheels. Just like a car, the two wheels are connected by a platform that you can build on, so four wheels, but two platforms. I hope that makes sense. :)

Ours has three wheels and it spins very easy, absolutely no hesitation at all.

I bought the 3 bikes version. I don't really wish that I had bought the 2 bikes version instead tho. It is nice to know that you can carry 3 bikes instead of 2 and that 1 bike space is pretty convenient to me. I always leave a space in between bike because it's easier for me to space them and tie them down instead of having 2 right side by side with a risk of scratching each other (I always tie them down so they don't swing around). Having 3 bikes on them kinda makes me worry because they don't seem to be the most stable rack out there. When I have 3 bikes I made sure to go slow. Most of the time I won't have up to 3 bikes tho.

Per the Specifications in Shoprider's owners manual, the turning radius on the Scootie is 40 inches. A wider 4 wheel base would result in a bigger turning radius. A three wheel always has a smaller radius. This is kind of a hybrid with four wheels but the front two close together. Bill Keene 954-421-3169 Boca Home Medical Solutions

Yes, it does appear to have power to all 4 wheels. However, if the weight isn't evenly distributed it will still struggle a bit with "off road action." We use it exclusively in our yard with small hills and it does well in all but loose gravel. Totally reccomend this product :)

It only comes with the two wheels. I never tried doing 4, but I'm thinking it would be possible if you bought extra.
