Is a recumbent trike faster than a non-recumbent bicycle?

I weight about 40 lbs (18 kg) more than the weight limit for the trike I can afford

Answer: Maybe - speed isn't the problem. While most "limits" have generous tolerances, your manufacturer's warranty could be unusable if there was a structural problem. Your brakes would have to ...

Can 3-speed 24/26" adult trike "keep up" with standard mountain/gravel bikes?

It is mostly not about the bike or trike, it is about the experience of the riders, their power and how easy they adjust. Without motor help a trike is usually slower than a bike, due to higher ...
