During my recent visit to Practical Cycles I was able to test ride a number of bikes including the Surly Big Dummy. I will be posting ride reports for the other bikes I test rode throughout the course of this week.
The concept behind the Big Dummy is essentially the same as that of the Yuba Mundo, the wheelbase is extended to allow an extra-long rear rack to be incorporated into the frame. The Big Dummy differs however in that the rear rack is not part of the frame, instead the frame is built to use the Xtracycle platform which can be used to convert most 26 inch/700C bikes into long-tail cargo bikes.
The Big Dummy is a significant step up in price from the Yuba Mundo, but this is reflected in the componentry included, and the cromoly steel used to construct the frame. By using the Xtracycle platform, all of the Xtracycle accessories are compatible with the Big Dummy. This was a big advantage over the Yuba Mundo a few years ago, but Yuba have since caught up and offer a much larger selection of add-ons and accessories.
Zaynan, the owner of Practical Cycles poses with the 8-speed Alfine geared Big Dummy
The standard spec complete Big Dummy comes with derailleur gearing, but Zaynan offers customisation options, the model I test rode was equipped with a Shimano Alfine 8-speed hub gear, complete with high-end trigger shifters.
I was particularly taken with the lovely Sturmey Archer chainset (this picture sadly does not do it justice, someone else has done better). At first I thought it was the hugely expensive SA chainset recently reviewed on Road.cc, but I was please to learn that it is actually only around £36. Now all I need is a bike which it will be appropriate for.
Sadly Yuba have stopped specifying Fat Franks for the V3 Mundo. Thankfully the Big Dummy still comes with this excellent tyre. The Xtracycle rack (unpainted tubing) fitting point can also be seen here, with the optional Wide-Loader stored away in the right Xtracycle bag, being installed in a similar manner to the main rack.
The model I test rode was also equipped with a front B&M dynamo light powered by a Shimano Disk-brake dynamo-hub. This is effectively the same light as my DL-1’s Lumotec Retro but in a more modern-looking package.
Using the Xtracycle platform enables Big Dummy owners to use the full range of Xtracycle accessories, including their heavy-duty kickstand
As for the ride, the bike felt instantly familiar to me. The steerer had thankfully been left at full-length and the bike had been equipped with moustache bars to give a more upright posture than the standard spec Big Dummy. The handling was almost exactly the same as the Yuba Mundo, but the rider position was more reminiscent on the Brompton M-type. For me this was perfectly pleasant, although the geometry and componentry of the Big Dummy are likely to appeal to someone who wants a cargo-bike which feels more like a cross-country mountain bike.
The Alfine hub was slightly smoother than the Nexus equivalent, the shifting was very precise and fast, even under load which is usually a problem for hub gears. The shifter was of the dual-trigger variety with one lever for shifting up and one for shifting down. This is the first time I have used this arrangement with a hub gear and I found it worked rather well. The Shimano disk brakes were as good as any of the cable-actuated discs I have used elsewhere and are an appropriate choice for a bike designed for load carrying and reasonable speed.
My impressions of the Big Dummy were favourable, but is it worth double the cost over the Yuba Mundo? If you are likely to spend a lot on upgrading the Yuba Mundo, the Dig Dummy may become more competitive price-wise. The frame is of a higher build-quality and higher-grade steel, but its load rating is lower. The standard rear dropouts (as opposed to the odd 14 mm dropouts on the Mundo) are more conducive to installing hub-gears, making any future hub-gear upgrades easier for Big Dummy owners than Yuba Mundo owners.
The upgraded specifications of the V3 Yuba Mundo do reduce the competitiveness of the Big Dummy in my opinion, although these have also increased the price. Personally, I enjoy the process of tinkering with, and upgrading my bikes. However, I understand that many people do not feel the same way. If you want the best componentry on your long-tail without the need to do a lot of upgrading, the Big Dummy could be for you.
Zaynan from Practical Cycles will be at the Chorlton Green Festival on Saturday the 16th of April. Amongst the cycles he will have with him will be the Surly Big Dummy, so if you want to have a closer look or a test ride, head down there.
