Can anyone suggest a USB rear mudguard specific light...the only one I can find that's any good is by Planet Bike?

Ah, not USB-rechargeable, just AAAs to run it.

EDIT: Apologies, as pointed out below it's a rack adaptor bracket, but it's easy to mod this to fit to a fender as it comes with nylock nuts and you just mount it vertically rather than horizontally (see here for the mount)

Do you mean rack adapter? If not can you provide a link please? I might get one.rangersac wrote:The cygolite hotshot has a fender adapter bracket you can purchase separately.

I looked at those but my Ogre with mudguards is usually placed on the handlebars and saddle for things like puncture repair and chain clean/oil etc. so I decided to stick with the tab I got welded to my Velo Orange Pass Hunter rack.Wingnut wrote:Ordered one of these so I can move my Edelux front light from the front rack to the handlebars...
I was worried about the handlebar mount making the bike off balanced whilst inverted
Great idea making the high rotating speed of the 16" trailer wheel pump out the power.
Much higher output with those rpm than my 29er or your 26 front wheel could do

Thats the rumour but I didnt notice any decernable drag difference between my 20' wheeled (406) Moulton compared to my 29er Ogre.Zcootz wrote:Higher output but with higher torque required to turn the wheel, more drag. No free rides
I'm not saying its not there but I never noticed it.
I'll be surprised if Wingnut does but look forward to his review.

Those "blades" should work equally well on a bicycles front dyno wheel as a trailer only needing the bike to be inverted instead of the trailer for successful wind charging duty "after hours".il padrone wrote:Extrawheel trailer modified to become an in-camp wind generator. Just requires a trailer wheel with dynohub, connected to e-werk to charge.

In truth a plagiarised idea from another forum rather than my own

Horror of horrors...... to up-end the bikerifraf wrote:Those "blades" should work equally well on a bicycles front dyno wheel as a trailer only needing the bike to be inverted instead of the trailer for successful wind charging duty "after hours".
I never up-end my bike. God forbid the damage to the Brooks; mucks up all the bar hardware as well, and the rear-view mirror. No there are better ways.
It's probably a legacy of my old road bike days with non-aero brake cables, you don't want to trash your cable housings.

It might but I doubt it.chillimagnum wrote:Could the Ewerk charge the Powergorilla?
The Powergorilla recharges at between 15 and 24 Volts according to the spec sheet I have. The supplied 240V mains charger outputs 16V/2.3Ah to the Powergorilla. Much more than a bike dynamo can produce.
It might be worth contacting Powertaveller themselves. IF the Powergorilla will accept a lower than specified input/charging voltage it may be possible but will take a long, long time to recharge off the hub.
Some time ago I came to the conclusion that charging a laptop on the road from a dynohub was not practical. Better off traveling with, and charging up a tablet that has much lower power (and space) requirements.
