 Topic: Making a better rickshawPosted: 07 August 2013 at 11:45am |
|
Hi,
currently am working on another improvement on the ultimate 'one less car' for families or better known as a pedicab (or rickshaw). We did a great construction for the kids from Children in Need, who did Cardiff to London and I think the weight came in at 65kg (not bad for a rickshaw) but this year am looking to develop on this. So my questions are, Has any one had any good or bad feedback on a Nuvinci 360 hub Has any one come across a good 26" MTB rim (48h and double walled), as Hope seam to have dropped making them. Any good (cost effective) 48h front wheel hubs and finally but not last a good set of hydraulic brakes for a trike? Thanks and if you want to see some past projects then either catch Bugbugs gallery page or my flickr pages PS happy to help in most ways, if you are making some strange custom pedicabs ;)

//Has any one had any good or bad feedback on a Nuvinci 360 hub I hear good things about them but not used them, check slip torque on the whlist you cart might be 65kg (say) your paypload could be somewhat more //Has any one come across a good 26" MTB rim (48h and double walled), with the advent of new/better materials would a 36 SS spoke not be ok? say on 3.2mm spokes? as yo are using in a high side load perhaps consider 150mm wide hubs. from the DH world. offent used on the older Orange. you could easy single side mount these with a 20mm bolt through. //Any good (cost effective) 48h front wheel hubs same as above 36h chainreactions.co.uk //a good set of hydraulic brakes for a trike? chainreactions again. not sure your going to get a good three set. and might be chaeper to buy three indpenadnts. you may have to make a one into two, so as to control the rear set as one. I have dies and taps for M8x0.75mm threads used in some of the setups and the others tend are M6. imho you need to use front sets on the rear due to the weight. or look at good DH calipers. Hope make a nice 6pot. second hand of ebay clocks in at about 50 quid. cheers and poblwc with the project Graydog |

Magura do a mirrored pair of hydraulic disc calipers - see here http://pedicabshop.com/blog/perfect-twin-disc-brakes-big-magura-twin.html for instance.

Bugbugs, the same site also has these http://pedicabshop.com/shop/spare-parts/wheel-parts/front-rim-halo-sas-24.html to answer one of your other questions, although they're 24", not 26".

When I upgraded a Mountain bike tandem with 48 hole rims - decided to go for a downhill 26 inch with 36 holes. It is pretty much bomb-proof! When I had it made up (at Merlin Cycles) they commented that this was the first 36 hole rim (or that type) they had used - but they had never had a 32 hole version back in for truing on any of the downhill bikes either!! So since I would never go for 48 hole rims on a 26 inch wheel any more for a Tandem - I don't see why it should be different for a rickshaw

using the smaller rims is very common, tyre choice gets limited I’ve found at the 24” relam. I used 20” (406) on the ones I built in South Africa. Although did use 20” (451) on one due to showing what you can do by recycling bicycles…. you can get some V-strong BMX rims on high hole counts |

I would talk to practical cycles as the Yuba Mundo Cargo bikes they sell (and I own) come with unbranded 48 hole rims (26") also so they may well be able to supply them....otherwise I know they stock..... Halo SAS Pro 48 in 26"
The Unbranded ones on my Yuba have done thousands of miles - bike weight 35 kilo rated to carry 200kg (of load) over the rear wheel. I've only had 100 kilos Load + 35k Bike + 75kg Me...but they are still going strong! |
