Maple Leaf Test Rides

The continuing saga of test riding a Supercycle SC1800 (Canadian Tire product # 71-1556)

SC1800 24233km

SC1800 is running well through severe duty. Regularly exposed to salty water, temperature around zero Fahrenheit and damaged roads, the machine is still riding well. The only maintenance since the last post was to lubricate the Shimano BRM432 brakes because a bushing was corroding, making the brake pad constantly drag on the wheel.

Lubricant of choice at the moment is Boeshield T9.

The light of choice right now is a Cygolight Metro 420. Works awesome so far. On the back is the Planet Bike Superflash, they been working quite well for awhile now.

SKYWAY km 2073.6


In November of 2012, this writer received a new machine to test ride.

It is a 2012 1/2 MEC Skyway - high lights are Gates Center track belt drive, Reynolds Chromium Molybdenum steel frame, etc . . .

The half year model denotes a running change where some models under the same stock keeping unit will fit fenders and others will absolutely not.

Upgrades within a month of point of purchase are: Wheels Manufacturing solid steel bolt on axles, swapping the drop handlebar for a regular MTB zero rise handlebar, 48/58mm reach brakes, Oury grips, Cygolite Metro 420 light, Planet bike fenders, luggage rack,etc.

At km 800 the belt failed when a stick went in it,derailled it, and then forced back on to the chainring.

Running pretty good right now, though there is quite a bit of wear and tear on the rim brake surface despite running soft salmon Kool Stop brake pads.

Stay posted for more observations . . .

km 23442.76

Back on like James Bond! Service interval of October 26, 2012 * Cateye odometer failed at 23233 after 923km. Failure due to open circuit in wyring harness. Replaced wih original Filzer Dz2L with a fresh LR43 battery. (apparently the LR44 also works adequately, but went with the original spec instead) Note: add 23233 to future odometer readings * Replaced broken back axle with cro-mo one...aligned dropouts more precisely this time. * Repaired back fender with Planet bike 'eyebolt'. * Replaced one broken spoke that failed at head * Replaced worn front brake pads. * Repaired failed weld in luggage carrier with tightly wrapped mechanics' annealing wyre. Service interval of November 28, 2012 * Repaired worn back tyre. Cords in outer casing had split, causing tyre liner to show through and ride wobbly. Back tyre is pre owned generic Kenda semi slick kindly donated by generous patron. * Removed badly damaged back mudflap from Planet Bike's 'Freddy Fender' * Noted wear on chain and oiled with Prolink * Noted missing paint and finish wearing off crankset * remarked how original front derailleur still works perfectly with no play between pivots, original grips in pristine condition, sticker still attached to stem.

Odometer stalled...

...around June of 2012 due to a fender failure (threw a rod holding on the back one). Since then, the 1974 CCM Galaxie 500 has proved an adequate replacement with it's Sturmey Archer AW 3 speed transmission and solid all steel construction. Looking forward to getting the SC1800 back in action ASAP and apologies for the delay in the observations in this experiment. dc

km 22835.1

22310 base

Observations are now taken from Cateye odometer that was repaired around mid-February, 2012.

Then, on March 2, 2012, the back derailleur was replaced with a Shimano RDTX35 (DATT model) (MEC part sku#264068 $12). A new drivetrain was hooked up from spares that included a new freewheel (MEC part#5020159 $13.50) and chain (MEC part 5006382 $14.50). This means the SRAM PC-830 was installed for 2431km, though it really was indicating worn out around 2000km. At that time the Filzer odometer indicated 6486km + 16000 (base km) which means the procedure was performed at interval 22486 km.

At that time the new Cateye odometer was indicating 176km which means there is 22310 base km to be added to future observations. The Cateye odometer is the same as a previous unit, except that it took this long to figure out how to change a battery (2032 type) to an instrument that is glued to the handlebar with cyanoacrylicate. Suffice it to say, it involves dental tools and patience. This procedure was performed just before the battery in the Filzer unit failed around the 23000 km mark. This means the unit ran for almost 6500 km at an average of about 20kph which means a run time of about 325 hours for the Filzer Dz2L with OEM battery.

Todays mileage reading is at 525.1 which means the machine has travelled 22835.1km.

To follow up on a previous observation: On May 13, 2011 a new back wheel and drivetrain was installed at interval 20055.1 km. The back wheel is spec'ed as [single wall aluminium rim, 36 spoke, Q/R aluminium hub] (MEC part sku#286592 $42). It was replaced as the solid axle in the old wheel was badly bent due to damaged dropouts. The dropouts were repaired and the new wheel is working out ok except that the brake surface is already 50% worn with 2780km on it. Also there was a single broken spoke repaired on March 2, 2012 at km22486, it seemed to fail due to having an 'elbow' of about 3mm even though the hub flange is only 2mm! Also on the same service interval the chain [SRAM PC-830] (MEC part #5016386 $14.50) and freewheel [Sunrace MF-M20] (MEC part #5020159 $14.50 at that time) were replaced.

The other maintenance involves disassembling, cleaning and lubricating the Shimano brand brake calipers. There is a bushing that corrodes quite easily and means that they can be closed to apply brakes, and then will not spring back to the open position. With regular maintenance this is not a problem, except that this services is being performed seasonally. Tried three different types of lubricant on the brake caliper bushing the results are the same. Stay posted to see if the 'Phil' brand grease will keep it from corroding by mid summer.

Other than all that maintenance, the rig is running quite right and tight with mightily gripping brakes and a solid hookup from the gears. The clock on the instrumentation is running on daylight savings time.

Replaced brake shoes due to necessity on January 22, 1012. The existing ones had worn to their wear indicators and then some.

Also the saddle is replaced at same maintenance interval with Planet Bike Comfort Classic (MEC part #5019910 $15) due to the fact the when the OEM saddle had snow melt into the upholstery, it would make for an uncomfortable experience.

Rig running right.

km 21709.9

Saddle upholstery badly degraded from exposure to sunshine UV rays for several years.

Grips are in great shape despite years of wear and tear and exposure to same amount of UV.

Drivetrain is past 1% wear line - spares chain and freewheel on hand once value has been extracted from product.

Computer now reads 5707.9km and battery is fading badly, yet cannot be easily replaced since unit is held on with high strength adhesive glue.
