The IQ Cyo is a cheap enough lamp that it's not unreasonable to have one on each of 3 bikes. That cost plus a dynowheel is equivalent to a high power, long runtime battery setup.

The biggest issue with the dyno (to me) is you need to have a battery backup like a mini-LED helmet lamp in case you have a breakdown or flat, since you can't use the dyno for that.
