Internal gear hub

A

Ashedog

Hello there,
Does anyone have any thoughts on using a Shimano Nexus 7 internal gear hub with a roller brake for the rear wheel of a Warrior trike?
Rather new to trike building and only just getting started when I found the hub on a scrap Dawes bike and liked the idea of no rear derailleur.
 
It's a good option. I see the Nexus series, especialy the 8, as a budget option for the WAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAY more expensive Rolhoff. But if you can, stay away from the Nuvinci/Enviolo hubs.

But the rear brake is a parking brake, not a real stopper. So, it doesn't matter that much. Rollerbrakes are easy to maintain, as it is the only kind of brake that wants to be greased.
 
There are rumours some of them have water ingress , so before you base the whole build around it find some online advice on how to service them.
It is super easy you dismantle one side and the whole internals come out as a complete package.
Some where it tells you to just immerse the whole thing in so many mm of oil for a few seconds then allow it to drip dry.

I quite like the roller brakes , I just greased mine once as recommended and they just keep on working.

Please DON'T use it in traffic ! as nasty things will happen if you do , however as mentioned with a friction gear changer they make a splendid parking brake.

Why steer clear of the Envolio? Do tell.
 
Be aware that any form of rear brake on a delta can be "interesting". If you brake hard during a turn, all the weight goes to the front and the rear unloads and can lock up and overtake you. I've had it happen. It's fun when you mean to do it and much less fun when you don't. Whether you can get it to do so will depend on the weight bias front to rear and your front brake quality.

I assume you meant tadpole ?

Delta Python trikes with rear brakes are interesting they bend in the middle and turn slightly away from a single braked wheel
