WorkCycles Secret Diamond Frame
Lugs and large diameter tubing make them much stiffer and stronger than frames from other manufacturers. They’re built to handle heavy loads and constant use. Frames are coated first with an anti-rust zinc carbonate primer and then a tough and environmentally friendly powder-coat. Your choice of standard matte black (all painted parts), matte army green or gloss anthracite blue. The WorkCycles Secret Service Diamond Frame bike have more of a svelte look compared to other classic bikes, with thinner fenders and tires. They are the lightest bikes of the classic bike series (2 kg lighter than the Opa) and have a slightly forward leaning riding position.
Fully enclosed chain-case and fenders
No dirty trousers/skirts and almost no drivetrain maintenance. The mudguards are zinc and powder-coated steel so they won’t break or rust. The full chain case keeps your drivetrain clean to reduce maintenance to a minimum. A hatch on the rear makes the occasional lubrication and chain tension adjustment easy.
Internal hub gears
All WorkCycles bikes have fully enclosed hub gears, mostly from Shimano: foolproof shifting, nearly maintenance free and out of harm’s way. You can even shift while stopped, a very handy feature when riding for transportation.
Hub brakes on both wheels
All models have a front Shimano roller brake and either a backpedal or (hand operated) roller rear brake. Hub brakes are nearly maintenance free, unaffected by weather and don’t make the bike dirty with brake pad sludge. WorkCycles fits the top of the line Shimano C-6000 roller brakes. Though many Dutch bicycles have only a rear coaster brake we feel strongly that a bicycle with two brakes is both safer and more convenient.
Hub dynamo powered LED lighting
Bright lights whenever needed without the hassle of batteries. The dynamo is inside the front hub so it runs silently with negligible resistance. Headlamps come from B&M in Germany and have powerful LED’s. The tail lamps have LEDs with a 100,000 hour lifespan and energy storage circuitry to remain on for a few minutes while stopped. Double wiring is routed internally though the frame and mudguard stays for reliability and clean looks. The headlamp can be upgraded to 50 lux with stand-light function.
Heavy duty 28” wheels
Special wide, double-wall, black, aluminum rims are made here in the Netherlands just for WorkCycles. These tough rims are laced with (thick) 2.3mm stainless spokes bent to precisely fit the hub. These wheels are so durable that they put those of other city bikes to shame. The tires are smooth rolling and long wearing Schwalbe Marathons with Kevlar anti-puncture layers.
DV or AV
DV are Dunlop valves on the inner tubes of your tires and AV are auto or ’Schrader; valves. Most cyclists in Europe will want DV valves and the majority of North American cyclists will find it handier to have AV valves. Both valve types work equally well.
Rear wheel lock
The integrated lock immobilizes the rear wheel. This won’t prevent the bike from being carried away but when combined with a chain or U-lock it’s a very complete locking system. For those fortunate enough to live in a low-theft area the ring lock is adequate on its own.
Brooks traditional leather bicycle saddles have been around for over 100 years and are still made in the UK. When you first receive a Brooks B67 or B67s saddle the leather is hard for around the first three months, after that it is quite comfortable. The leather slowly softens and forms to the shape of your sit bones. Brooks saddles are not for the heavier rider though, we recommend a rider weight guideline of around 80 kg maximum. You need to care for them as well, treat the topside with Proofide every 6-12 months and keep the underside dry. If possible store the bike in a dry place between rides so that the leather can dry out naturally. Use the saddle cover when the bike is parked outside in bad weather and remove the saddle cover when you ride the bike. Tension the leather when necessary, if the leather is touching the saddle rail it needs to be tightened. We sell a complete saddle care kit. If you prefer not to have a Brooks on your Secret Service you can swap it out for a Selle Royal Ondina or Lookin saddle.
Stainless steel parts and hardware
The handlebar, stem, spokes and almost all of the nuts, bolts and washers will remain serviceable and pretty for years… even when stored outdoors in a rainy climate (like Amsterdam).
Stable and strong centerstand
We find the combination of this stable, 2-leg center-stand, steering limiter spring and the headlamp mounted on the left fork leg to be much handier than the more typical side-stand. The bike stands upright which is great when loading the front carrier and even with loaded panniers or front carrier the bike stands reliably.
WorkCycles Secret Service Diamond Frame Options
Frame mounted front carrier
This incredibly handy rack is fixed to the frame so it can carry huge loads without influencing your bike’s handling. Your bike remains stable when parked as well. Once trying a bike with a frame-mounted front carrier you won’t ever want to ride a bike with a load that swings around with the front handlebar. It can be removed with a single bolt, but once you’ve used this carrier you won’t understand how you ever lived without it. Most WorkCycles riders choose to semi-permanently attach a crate to their front carrier.
MT Crate & Crate mat
This is the WorkCycles crate, measuring 50 x 30 x 20cm it’s perfect fit for your frame mounted front carrier. Just drop your grocery bags, backpack, briefcase, kids toys in and go. The additional MT Crate mat functions as anti-noise mat, locks and groceries don't rattle around anymore.
We sell the Brooks Plump, Slender and Cambium Comfort grips. Plump (Thick) and Slender (Thin) are traditional leather grips that match nicely with your leather saddle. The Cambium Comfort grips are modern rubber handlebar grips with organic cotton for a natural look and feel.
Selle Royal Ondina or Lookin saddle
Brooks leather saddles are not for everybody and if you’d like a Secret Service bike, but would prefer a no-fuss saddle then you can choose an Ondina or Lookin saddle from Selle Royal. The Ondina is out most sold saddle, it’s practical and perfect for around town riding. If you spend quite a bit of time on your bike on go on longer rides then you’ll appreciate the Lookin as it’s more comfortable than the Ondina. The Ondina and Lookin and both synthetic saddles and retain their shape.
