I am sure most of us who are old as dirt like me remember the generator dynamo light sets we had on our bicycles. They worked, but the amount of light varied according to the speed we rode. They could be very dim or we could ride so fast that we could burn out the bulbs (which I did many times). In short, they lacked good technology to better regulate the power being produced. Yet they did work. We have certainly come a long way when it comes to bicycle lighting. I only mention these old generator dynamo light sets because what I am writing about here is something which looks very much like the generator dynamo of old.
This new generator dynamo very much incorporates modern day technology, but its purpose is not to produce power for lighting. Nope, this unit provides 5 volts of D.C. current for a USB outlet so we can power up all sorts of modern day electronic gadgets to charge them as we ride. I don’t know much about it, but I find it intriguing.
The cost is reduced to about $33. However, the website shows it is “currently out of stock”.

Keep in mind that this product is designed to use on a standard bicycle so using it on a tadpole trike might involve some ingenuity mounting it so it would line up properly and work on a trike wheel. Some trike frames might be more challenging than others. Of course, it could be operated on any one of the three wheels of a trike. I assume that sooner or later it will be back in stock. The website does provide an email service to notify when it is back in stock. I really like the idea of being able to recharge a cell phone or other devices … and doing so while we are riding. It all helps us …
ENJOY THE RIDE
