Smooth transaction, delivered on time, Packed very well.
Straight forward assembly, if your child is tall, go for the 2nd nearer of the fixing point.
On first 100m test run, noticed slight chain/sprocket noise. Lubed the chain with quality chain oil, zero chain noise.
Throttle span responce isn't linear regardless of setting, so just be aware. ( minor observation).
Other than that, powerful, and good quality machine for the price. My lad absolutely loves it.
