Re: What type of hub is this?

Try googling hollow bicycle hubs... I have a trailer that uses push button axles for a quick release. The hub your showing looks very similar. You"ll need to find an axle and bearing. Check the parts at Wike Trailers http://www.wicycle.com/index.php/parts-and-support/ See different hubs here https:/...

Re: Hub motor More power for coffee trike

I agree with the Mid-Drive and a large single speed freewheel.
Considering you are after torque, not speed.
I don't know how large they come, here's a link to 24 tooth.

I'm sure there are other options for freewheels as well....

Re: Took my 13 year old son for a ride today.

I built this scooter for my son, (48vdc / Mac) he's having great time. Often when we get home, he says, "that was so much fun!" Oh, he's 10 years old. Later we'll work on a bike.

Re: Advice requested for e-bike kit for Yuba Mundo

I think allot depends on what battery you'd choose....

You should consider batteries with 20 AH or larger.

36 to 48 medium current - Geared Hub, they have good torque.

48 and above, medium to high current - Direct Hub

Chalo's word are harsh, but true.
Crazy e-bikers jeopardize the rest of us!
None of us want more regulations and scrutiny...E-biker who want to surpass the laws, should take it off-road (hopefully private property) or to the track

Re: advice? 150+ Mile commute - Fast/super charge options

A propos making a homemade trailer, I recently discovered these hubs, which even I can afford: Image They don't look like much, but they have bearings in them, they come in 5/8"and 1/2" axle versions, and they retail for ten bucks. I think they're US made. I built a nice pair of 26 inch radially la...

I don't know the size of your drop outs. but most IGHs axles are smaller than the many drop outs. Perhaps they've opened up as well?!

Re: Bakfiet 'bakers bike' Holland

I agree, 250 watts is not enough power. 1000 watts would most likely work, especially in a mid-drive system. I have a 48volt mid-drive Yuba Mundo (about 100 lbs+), it delivers 1400/1500 watts while going uphill, carrying my Son and I (another 330/340 lbs) fully loaded with stuff, Also, sometimes we ...

Paul, I don't know enough about these bikes to be helpful, related to the correct mid-drive. Does the manufacture have recommendation for electric power? It seems you done your homework as far as measurements. Perhaps Paul (cellman) or Eric (Luna) can offer some help on what might fit. Even Justin (...
