After a lot of trials, I found out what was wrong with the trike. I went to a bike shop and was told that I need to make a triangle to hold bottom bracket, that didn’t seem to really be true. I started to notice what was the problem, and it seemed it was the bottom bracket was shifting. So I wanted to test my theory, and notice that on a regular bike that you can pedal from a standstill position without too much effort. I therefore decided to ensure that my trike could pedal from a standstill. I was able to do that and there was one ride where I actually went up a steep hill. I noticed it wasn’t very difficult to pedal and I have been trying to replicate that ease of use ever since (making sure that I don’t pedal with extraneous effort). Below is a the video of my success. I know how to make this trike to be a great trike, but at this point I’m not sure if I want to continue to work on this one or go on to the next model. I just got a bike recently and it pedals fabulously, and I want my trike to be able to pedal just like it. Then I’ll know I have accomplished what I wanted to accomplish.
