I’ve had Power Grips on my DIY Delta Trike for a little over 30 days and I’m still using them. I guess if I’m still using them, there must be some good in them. Pedaling in circles had increased my speed a couple of miles per hour over my speeds with just the platform pedals and that’s one of the main reasons for having something that will attach my feet to the pedals. BUT!
When I bought the Power Grips, I had several things that I was looking for in locking my feet to the pedals. One was, of course, to improve my pedaling efficiency which would in turn increase my speed and/or my endurance. There are not many things that will improve my speed by 2 miles per hour for only $30.00. So, I’m happy with that aspect of the Power Grips.
A second objective was the Power Grips should hold my feet firmly to the pedals. In the reclined position of the recumbent there is a certain amount of danger in your feet falling off the pedals and making contact with the ground. That has happened a couple of times and it is somewhat scary. The Power Grips work fairly well at this, but I find my feet slipping out of the straps and needing to push them back in the straps from time to time. All in all though, they are OK at holding your feet on the pedals.
I still have some of the negative issues that I had on the first day of riding with the Power Grips. In the reclined position, I still find it hard to mount the pedals. I think on an upright, you have more freedom of movement and this would be a less frustrating task. Laying on your back while holding your leg in the air and turning your ankle out far enough to slip your foot into the strap while using your toe to keep the pedal upright is quite a task. I don’t have a solution to this problem, but I’ve learned to deal with it a little more quickly.
Another objective I had was to be able to wear a variety of shoes when I ride. I’ve adjusted the straps to fit many of the shoes that I might use to ride my trike. I’ve not tried dress shoes, but all of my tennis shoes/running shoes seem to work well with the same strap setting. I can even force in my high top (protect me from snake bites) lace-up work boots. This they do well. BUT!
But when I’ve adjusted the straps tight enough to hold my feet firmly to the pedals, they really put a lot of pressure around my foot. When I release my foot from the pedals, there is a sensation of pins sticking in the bottom of my foot. They do get quite uncomfortable on longer than one hour rides.
I think most of my negative issues with the Power Grips are because of my very reclined position on the trike. Holding your feet firmly to the pedals so they do not slip off and strike the ground would not be such an issue on a less reclined trike or an upright bike.
I’ve also developed knee pain since using the Power Grips, BUT. But I’ve also become a stronger rider over the last year and putting more pressure on my knees. I don’t think the Power Grips are the real problem. Still working on this.
All in all, for the investment, I think they work OK. I’ll still be looking for a better solution but keep using them until I find one.
