There are no problems with the vehicle; it is completely fresh, just like brand new... excellent pull/acceleration... runs 70-80 km on a single charge... has 6 batteries... a sight to behold... the braking system is very good, stops wonderfully... hydraulic brakes on both wheels... I have taken it up to a top speed of 70... and the suspension/shock absorbers are very good... high-end wheels installed which are much thicker than standard e-bikes, making the ride a lot of fun... absolutely zero motor sound while driving... completely waterproof, no issues if it gets drenched in rain or washed with water... it cost me 145 [thousand], will sell for 95 [thousand] Inshallah...
