Love this quirky coolest of e-bikes

I searched long and hard for a bike which wasn’t a mountain bike because the riding position hurts… not girlie because ribbons and long flowing hair with daisies in just isn’t me. I wanted quirky and this is what I got when I found the Super Monkey. As a kid I always wanted a Chopper….this is 100x better than a chopper. It is totally gorgeous, so comfortable, easy to get the hang of and I would recommend to anyone. I am 5’8” and it is a lovely size for me. My son is approx 5’10 and he finds it comfy too. I got all the upgrades, forks, thumb throttle, mud guards, lights and rack. Worth the extra pennies as my little monkey is ready for everything now. I intend to fix a dog carrier on the back and go for adventures with my Border terrier…

I’ve purchased two bikes from Synch over the last year and couldn’t be happier with them! They are so unique and offer a riding experience that I just couldn’t find elsewhere. I truly love the Back2Black Super Monkey, it fits my style perfectly. Plus the addition of the lights and mudguards made it practical all year round! Having said that, I’ve owned my 250w Super Monkey for a good few months now, clocked over 300 miles and covered distances of more than 35 miles per trip from one charge. Absolutely brilliant! If you’re thinking about pulling the trigger on one of these bikes, don’t hesitate! Best decision I made.
