KT-E60 — Dual-Voltage Integrated-Frame Platform

The KT-E60 is the platform most integrated-frame programmes settle on, because one enclosure and one frame cavity cover four electrical configurations. The 425mm pack body and 465.5mm down-tube channel do not change between 48V and 52V, or between 18650 and 21700 — which means a brand can launch on 48V, add a 52V variant for a different market, and switch cell format when supply or cost moves, without a second frame tool.

The four builds are: 117 cells in 13S9P for 48V 23Ah, 126 cells in 14S9P for 52V 23Ah, 78 cells in 13S6P for 48V 30Ah, and 84 cells in 14S6P for 52V 30Ah. Read those as two decisions rather than four options. Series count picks the voltage platform; cell format picks the capacity tier.

Where the KT-E60 sits against its neighbours

Against the KT-E57, the KT-E60 needs about 60mm more frame channel — 465.5mm against 405.4mm — and returns 23Ah to 30Ah instead of 15.6Ah to 20Ah. Against the KT-E60-PRO, the pack body length is identical at 425mm; the PRO is taller, and that height is what takes it to 40Ah. So the choice between KT-E60 and KT-E60-PRO is a down-tube depth question, not a length question, and it is usually decided by the frame designer rather than by the battery specification.

Current rating and BMS sizing

All four builds are 8P-class arrangements, so 40A, 60A and 80A continuous are all available — unlike the KT-E57, where the 6P build is limited to 40A. This is the platform to specify when the bike carries load: cargo and mid-drive systems draw sustained current that a low-parallel pack cannot supply without sagging. Enclosure sealing is IP67 with UL94 V-0 housing material, and the UN 38.3 report and CE Declaration of Conformity are issued per configuration — a 52V 14S9P build does not ship on the 48V pack’s paperwork.
