Here is the final part of the Bestrider Pump Pro 20 kids bike assembly! All the components that I wanted to upgrade has already been installed successfully.
Toseek carbon handlebar, cut down to a width of 520 mm.
Using the stock Tektro brake levers, but with a shorter 95 mm lock on grip.
Using the Deore XT Trekking SL-T780 10 speed shifters, with a light shifting action.
Stock 35 mm aluminium stem with oversized 31.8 mm clamp diameter is used
Sweet looking 1x10 speed drivetrain!
Using the stock crankset and chain ring, with colourful chain ring bolts. Super smooth spinning Early Rider pedals are used here.
Changed to Shimano SM-BBR60 bottom bracket.
Left crank arm looks exactly like the Shimano design, except for the crank arm fixing bolt.
Stock Tektro V brake calipers, but changed to polymer coated brake inner cables for lower friction. Check out this post for more details on the Continental tires!
Chain at the top gear, on the smallest 11T sprocket.
Rear derailleur cage still has quite a bit of capacity, seems that the chain could have been longer.
Chain at the lowest gear position, on the largest 36T sprocket.
Cage looks rather stretched, could have added a couple more links.
Full bike view from the non-drive side
Stock kickstand, and using lightweight quick release axles.
Full bike view from the drive side. Looks really good!
Complete bike specifications and weight. 7.4 kg without pedals and kickstand!
Actual weight of 7.8 kg with pedals and kickstand matches the calculations.
Bringing the Bestrider Pump Pro 20 kids bike out for a test ride!
I'm happy with the weight of the bike, at 7.8 kg with pedals included, and a 1x10 speed drivetrain. There are many single speed kids bikes that weigh more than this, so this bike is really lightweight.
There were no complications with the modifications of this bike, as the bike frame has standard specifications, while all the components used are pretty standard.
