High-Power Motor Performance The EM-5 PRO uses a brushless motor with 4000W peak power on a 60V platform. The listing claims 0 to top speed in ~5 seconds, with a stated top speed up to 70 km/h (44 mph).
Battery & Range A 60V 27Ah lithium-ion battery is listed, with an estimated range of =50 miles when ridden steadily around 25–30 km/h. Charging is listed as 7–8 hours, using a 60V 5A CE-certified charger and AC110–230V / 50–60Hz input.
Off-Road Wheels, Suspension & Control The bike runs 17" front / 14" rear off-road tyres and uses hydraulic disc brakes front and rear. The listing also states IPX6 waterproof rating and a minimum ground clearance of 23 cm.
Climbing, Fit & Build The listing mentions climbing ability up to 40° in one section and 30° elsewhere, so it’s worth treating climb performance as terrain-dependent. Frame material is listed as steel, with a maximum load capacity of 130 kg (287 lb).

Frequently Asked Questions
This bike is best suited for and the recommended rider height is between 150–185 cm.
Yes. The Pro uses 17/14-inch wheels and an 80 cm seat, compared with 14/12-inch wheels and a 72 cm seat on the standard EM5. It feels more substantial and is the better choice if the standard bike feels too compact.
The larger 60V 27Ah system gives the Pro more stored energy and stronger performance headroom than the standard 48V EM5 platform. It is aimed at riders who want longer sessions and a more serious off-road setup.
TrailSurge currently lists around 7–8 hours for the 60V 27Ah battery. That makes overnight charging the most practical routine if the battery has been heavily used.
No maximum-range figure should be treated as guaranteed. The listed 50 miles is achievable only under favourable conditions; hard acceleration, higher speeds, hills, mud, cold weather and rider weight can reduce it substantially.
The Valtinsu EM5 Pro Electric Dirt Bike is water-resistant and suitable for riding in very light rain. It is not fully waterproof and should not be submerged. Short term, your product can get a little wet and be in the rain, but any long-term exposure can cause serious problems.
Really impressed with the Valtinsu EM5 Pro Electric Dirt Bike so far. Power delivery feels lively, the stance is good and it feels like a serious bit of kit for the size.
