Cinder Cone high speed commuter

Smithers BC

106

I turned my old Kona Cinder Cone hardtail into an excellent commuter with a bunch of components from Grin.
I think that a barrier for a lot of people who might be interested in converting a bike (certainly me!) is a distaste for protruding clamps, wire bundles and zap straps. I set out to make this bike as close to the slickness of a factory ebike as possible, while still enjoying all the advantages of Grin components (power, customizability, future-proofing, regen braking, throttle and torque sensing . . . ). I got most of the wiring inside the bars, concealed the torque arm, and streamlined the battery mount. See what you think from the photos.
It has a 10t Gmac motor capped electronically at 1500 watts (which it easily reaches), a 52 volt battery, Erider bottom bracket torque sensor, and other components explained below. I charge to 85% with a Satiator to prolong the battery life. I can ride at 40-50 km/h anywhere my car goes now, and get to work non-sweaty if desired. I have programmed a fully street legal mode in case of compliance issues, and an offroad mode (which I use most of the time). I think of it as a wolf in sheep's clothing.

motor and torque arm

I chose a Gmac motor for plenty of power and torque on hills, and regen braking. I wanted a rear motor because I also use the bike for logging road and trail access for hiking trips, and a front motor would have spun out too easily on hills.

Controls and wiring

I took a long time to get the wiring as tidy as possible on this bike. I ordered a new stem and larger diameter handlebars to allow space for wires and connectors inside both.

Rack and wheels

I mostly use this bike for commuting on pavement, but also for backcountry access on trails and rough roads, so it had to convert quickly to rough surface use.
