Cargo Bike


I’m planning to launch a new business early next year as a mobile bike mechanic. I had thought of buying a 1990s Nissan Micra hatchback as transport for the business but I’ve settled on a long tailed cargo bike instead.

The Xtracycle Freeradical
A cargo bike has several major advantages over a car, the main one being cost. Even a small used car like a Micra is going to cost over a thousand euros to get on the road. And the costs are only starting then, fuel, motor tax, insurance, road testing, repairs and servicing. I would have to make several thousand euros a year just to pay the transport bill.

I had thought of buying an Xtracycle Freeradical which is a frame that bolts onto the back of a bicycle, moves the wheel back 15 inches and converts any bicycle into a long tailed cargo bike. I decided against the Xtracycle Freeradical because some reviews suggested there is some flexing of the bike frame when heavily loaded, the accessories are quite expensive and it can only carry 85 kg (combined weight of rider and cargo not to exceed 160kg).

The Yuba Mundo
I’ve finally settled on the Yuba Mundo a purpose built long tail cargo bike, which can carry up to 200 kg of cargo. I doubt I will ever carry anything close to this kind of load but it’s good to have the option. For most people the Xtracycle Freeradical will do the job.

I’m buying the Yuba Mundo frame set, wheels and kickstand from Practical Cycles in Lytham, Lancashire, UK and will build the bike myself. I have a second Raleigh Oakland and will strip it for handlbars, saddle, gear, brakes, etc.

Unladen the Mundo will weight about 21 kg. My full bicycle repair toolkit, workstand, spare parts and the framework I’m planning to build on the back of the bike, will weigh about 30 kg. So I should be on the road at 51 kg. The countryside in which I live is hilly so I’m going to settle on a maximum range of about 15 miles from home. If all else fails I could add electric assist to the bicycle and increase my range and cargo carrying capability.

The Yuba Mundo Frameset
Perhaps the greatest advantage of a cargo bike from a business angle is there are none where I live. A cargo bike will really stand out and will be a great way to promote my business. What better way to run a mobile bicycle repair business that with a cargo bike.

I’ve also started to notice that there is a lot timber along the roadsides around home. So my first plan for the cargo bike is to make some kind of frame for carrying firewood and to go cycling with a bow saw and haul lots of free firewood home.

Dynamo Bike Lights


In a major upgrade to my Raleigh Oakland I’ve just added a Novatec dynamo hub and a Philips SafeRide LED Bikelight Dynamo 60 Lux. I built a new front wheel using the Novatech hub, a Mavic 2013 A119 Road Rim and 36 DT Swiss Competition Stainless DB Spokes.
Novatec Dynamo Hub

I got the hub from Alf in the Bike Inn when I was doing the bike mechanic course, he charged 25 pounds sterling, they are available from Amazon for 30 pounds sterling. The dynamo hub generates a lot more friction than an ordinary hub, when spun hard the wheel will do a few revolutions before coming to a stop, but I barely notice the added resistance when riding the bike.

The rim and spokes came from Chain Reaction Cycles. To build the 700c wheel with the Novatec hub I used 288mm spokes.

The Philips SafeRide LED Bikelight Dynamo 60 Lux light came from Bike24.com in Germany and cost 60 euros. This is a very bright light, much brighter than the Cateye EL-135, battery powered light it replaces. Most of my night cycling is done on dark rural roads and the Cateye EL-135 is not bright enough to see hazards like pot holes on a wet night. The Philips light floods the road ahead in light and will stays on for up to four minutes after you stop, useful for cycling in urban areas.

Philips 60 LUX Dynamo Light
Only time will tell if this investment is worthwhile. Modern battery powered LED bike lights are so efficient and cheap to buy and run that it will take a very long time for this outfit to pay for itself (and I still have to invest in a back light). There are cheaper LED dynamo lights, Raleigh do a 40 LUX dynamo light that sells for about 16 pounds sterling. But however the costs work out in the long run I’m getting a great kick out of lighting up the night with my own power.

New York Bicycles After Sandy


Among the many virtues of the bicycle is its simplicity. A disaster like Hurricane Sandy can take out complex systems like the power grid and subway but the bicycle will still work. Even if the roads are blocked with fallen trees the cyclist can lift their bike over obstacles.

In much of New York right now the power grid is still down but on the lower East Side volunteers from the environmental group Times Up are running a free tandem powered mobile phone charging service. In times of trouble maintaining communications is vital and the small amount of power needed to charge a mobile phone can easily be supplied by a bike.

With the subway closed, car access to Manhattan restricted and many filling stations out of fuel the bicycle is really coming into its own for commuters. On the website http://bikeapolis.us/ there are details of community organised support stops for cyclists, offering mechanical help, coffee and emotional support. There are also details of Bike Trains where commuters can meet and travel in groups for safety.


Bike Portland have a series of good posts about the bicycle in New York after Sandy
