Hi! Thanks for your response!
I'm not dead set on the D7 (not yet purchased). But I am dead set on a small folding bike. Would greatly appreciate alternative recommendations if you think the D7 is too flimsy! Or, let me know if you think no small folding bike is up to the task.
If I do go with...
I have a Bafang middirve + 52v battery mountain bike build that I'm enjoying tremendously. Now, for my next project, I want to build a 20"-wheel folding rear-hub-motor e-bike for inner-city commuting. For my base bike I will probably use a Dahon Speed D7.
My question is what kind of hub motor...
Pictures of the shim attached. Excuse the dirt; haven't gotten around to cleaning after yesterday's ride. The shim is the thicker one of two that arrive with this http://amzn.com/B002T5GHNI and folder over. At first I didn't fold it and while the gears wouldn't get completely stuck they would...
Any one ever try one of these: http://www.edibike.it/prodotto/corona-doppia-4248-denti-per-suzhou-bafang-8-fun-centrale-bbs/
It's a double chain ring machined especially for Bafang BB0x. I suppose it's made to wrap around the motor like the stock rings to get the right offset -- which you...
I also use a thick rubber shim to separate my aluminum frame from the BBS02 unit. I think this shim came with a seat-post-mounted rack. I put it there originally because otherwise the unit would eventually push up against the frame and the shifter cable and make my gears stuck, even if I...
Some old full-sus bikes, like the 2002 speciazlied stumpjumper pictured below in the attachment, have bottle-cage mounting points on the underside of the down tube (in addition to mountin points inside the triangle). Such full-sus bikes have too small a triangle to fit a frame mounted "dolphin"...
I have a motor/controller combo that's rated 48V 750W 25A (it's the BBS02).
Q1: Why don't these numbers match up? 48V * 25A = 1,200W =/= 750W. What is the physical meaning of each of these numbers? Does the number relate to the motor, controller, or both and how?
I have a battery pack that is...
wesnewell, sorry about that slip. I did read that post you linked but my eyes glossed over the location part. Hope that helps suggest vendors.
Avitt, thanks again for the input. Thanks, melodious. So IGH+middrive is not a fantasy! (Maybe only in my budget but I'm excited enough now to spend a...
For everyone who posted $ dollar amounts (Ykick & wesnewell), could you please post links to vendors/product pages? Thanks! And thanks for the advice.
Thanks for the input, Avitt. It seems you were in a very similar situation as me. It is very encouraging to read about your build! Question: in...
Ok. Thanks for the wise advice re commuting. You're definitely right.
And thanks wesnewell for the suggested work around. Think I'm gonna go with that. Where could I get all that for $500 inclusive? Thanks again.
Thank you everyone for your helpful feedback. I'm a bit discouraged you think my bike is not very convertible. I'll try to make the most of it. I'm surprised everyone is so hesitant about the IGH. I've seen others use them with mid-drives (this guy...
Hi motomech. Thanks for your response. Why would I be stuck with front mount for mid drive? A mid-drive motor would run my rear IGH if I understand correctly. Maybe I didn't understand what you wrote.
Hi ES.
First timer here looking to electrify my bike.
I recently moved to LA and refuse to commute by car. Living previously in Boston, I transported myself everywhere on a conventional bike. But distances are much greater here so I want to electrify my bike to transform it into a commuting...
