Giant

Shimano Double Sided Bike Pedal

The pedals the Giant comes with are really cheap. I wanted pedals which could accommodate my Shimano cleats and also let me ride in regular shoes around town. These things are great. Have them on my Fuji Cross hybrid too. Bought on Amazon. Yeuch! Ugly scratch on my battery case. Hit a pothole and it flew off the bike coming down a hill doing about 30mph. Made a heck of a crash as it landed. My fault - had not locked the battery to the bike!

Lekkie Chainwheel (46T)

Called a "bling ring" and available on the various Electric bicycle websites. I bought mine as part of my kit from ElectrifyBike.com. Mine is a 46 tooth chainwheel. Every second tooth is the same size...there being two sizes, one narrow and one fat. Helps grab the chain better for when one is in lower gears and pushing hard up hill - prevents the chain from coming off.

Hexlox Hub Security Spindle

I bought these for each wheel and the seat post. They replace the bolt or the quick release hub with a spindle that has its own secure nut which in turn has a little magnet inside it which you need a special key to extract, and then you can just use your Allen key to remove the wheel. I carry a little Topeak toolset with me always. Careful not to tighten the nut too much (like I did first time - necessitating getting another having stripped the threads).

Cane Creek Thudbuster ST Seatpost

So far, this offers a suggestion of rear suspension. Its hinged mechanism up near the saddle has a chunk of polymer in the middle which absorbs the impacts. I hindsight I really don't need it but every little helps I suppose and on longer rides I imagine it begins to pay its way. I'd say I would only notice it if I went back to riding without it and bog standard seatpost. So far my rides are no more than 25 miles but when I do go further I imagine this will become a fast friend.
