Curious how the two compare. Am deliberating between a DIY DD hub kit with the TDM sensor and a Juiced Bikes Crosscurrent or Copenhagen Wheel for a car-replacement loaded commuter purposed ebike. Commute is 7-10 miles one way (14-20 miles round trip)...
My budget is ~$1,200 (<$1500 minus cost of a Cycle Satiator)
My donor bikes are either a singlespeed Wabi Classic or my project bike 26er that I might build up... http://wabicycles.com/shop/bicycles/wabi-classic-standard/
https://stlouis.craigslist.org/bik/6022381685.html
Current view of either path below
DIY DD Hub Build (US$830.74) + 48v 17.5ah battery (US$830.74 from LunaCycle)
Pros:
- Stronger/faster, non-governed motor (9C+... also considering All-Axle from GRIN but more $$ and still in beta)
- Modularity (in case of Copenhagen Wheel)... I can access, service, and replace/upgrade parts/battery as desired with more options*
- Will probably be fun to build and tinker
- Regen! Save my brake calipers!
- BIGGER MOAR POWERFUL BATTERY YEAH? (inner Bruno)... possibly better battery cells used through luna/e3mev
Cons:
- Modularity (in case of Copenhagen Wheel)... I can access, service, and replace/upgrade parts/battery as desired with more options*
- My donor bike has caliper brakes/my wife is concerned I'mma gonna go too fast and kill myself....
- Cable/component management (i.e. clean looking bicycle)
- Complexity of setting up desired features... (torque sensor)
- Connectors/adaptors/Sourcing parts from different vendors.. wait time... ebikes.ca for motor/accessories, battery from e3emv/lunacycle
- Rust?... long-term durability performance concern
Copenhagen Wheel ($1,248.00 w/ shipping if bought before March 23... promotional period)
Pros:
- Clean, single integrated solution*
- Sensible assist levels
- Seems to be good integrated torque sensor capability
- Regen! Save my brake calipers, already configured.. easy!
- Can use my existing bike which I'm comfortable with... since not as fast, not as concerned about road calipers
Cons:
- Concerned about battery life/lack of modularity for user changeout.. 5aH battery... 30 mile range?
- Not exciting assist levels
- Range issues inherent with battery size/modularity
- Donor bike has road calipers... weaker motor, but still.. possible braking concerns?
- Sealed better? Less rust issues? Concerned about warranty wording with regard to water damage
Juiced Bikes Crosscurrent ($1,100)
Pros:
- Complete bike... allows me to save my single speed wabi as back-up commuter bike.
- Integrated torque sensor/PAS assist... supposedly real close to a normal bike in ride feel
- More appropriate commuter bike features (rack mounts... I found out I cannot fit my old bike rack/panniers on Wabi since no mounts)
- Hydraulic disc brakes.. probably lot safer
- Faster than copenhagen
- Modular systems.. battery... motor... torque sensors... *
Stock battery .. 7aH... possible to use as backup later
Cons:
- Hydraulic disc brake maintenance?
- Not as fast as ungoverned DIY hub set-up..
- Geared hub... no regen
- *Proprietary modular systems... replacement/upgrade batteries little more costly (48v 17.5ah @ $999.00)..
Based on these values... broke out into requirements matrix: https://docs.google.com/spreadsheets/d/1jnKSJ3xmBv1Cds6w1w6UKzTrkf19yE3qEmXuXKYmZLU/edit?usp=sharing
