Is "Ares*2" a different model?+
No. It is two bikes. AMYET’s Style option on this listing offers "Ares" at $1,099 and "Ares*2" at $2,099, and the second is a pair of the same bike rather than a larger battery, a stronger motor or a longer frame. Every specification on this page describes the single bike at $1,099.
How far will the Ares go?+
AMYET does not say, which is unusual — they publish a range band for the K10, the G60 and the EB26. What we can do is the arithmetic. The pack holds 1,040Wh. At around 20Wh per mile, which is a fair figure for a fat-tire bike with one motor working on moderate assist, that is about 52 miles. Drive both motors on soft ground and 30Wh per mile is easy to reach, which brings it to roughly 35. Treat those as estimates of ours, not claims of AMYET’s.
Is 52V better than 48V?+
It is a higher voltage, not automatically a better battery. What matters for range is watt-hours, which is volts multiplied by amp-hours: 52V × 20Ah = 1,040Wh here, against 48V × 25Ah = 1,200Wh on the S8. The higher voltage does tend to hold motor speed better under load, which suits a bike sold for climbing, but it is the 1,040Wh figure that sets how far you can go.
Why does the battery capacity appear twice on AMYET’s page, differently?+
Two separate wrinkles. First, the product’s web address says 25Ah while the title and body both say 20Ah — the address is stale and 20Ah is what AMYET currently publishes. Second, the listing carries an energy-content field inherited from a marketplace template whose value is wrong for a pack this size by a factor of hundreds. Neither is a specification. We print the 20Ah figure, which gives 1,040Wh, and disregard the rest.
Ares or S8?+
Both are dual-motor AMYETs with a 3000W peak claim. The S8 costs $1,049, carries 1,200Wh, has full suspension and — the deciding difference — states hydraulic disc brakes. The Ares costs $1,099, carries 1,040Wh, folds, and states only "disc". If you do not need the fold, the S8 is the better-braked bike for slightly less money. The fold is what you are paying the difference for.
