Who should consider it
SB20 is strongest for riders who want used smart bike value. It looks most appropriate for advanced riders based on price, power, accuracy and stored review signals.
Check first
Setup and trade-offs
Check discontinued/support uncertainty before buying. Also confirm cassette, axle and app compatibility for your own bike, especially if you are buying used.
Market note
Discontinued
SB20 is mainly useful as a used-market reference. Condition, accessories and firmware support matter more than launch specs.

Grouped specs are easier to scan than a single long table. Unknown means the stored sources did not confirm the value cleanly.
