from 45 reviewsThis is my first electric bike and I was very excited when it was delivered. It looks powerful, streamline and felt amazing when I got on it. I got my own seat for additional comfort, for personal choice as it's not really needed.
Having not been out bike riding for a while and lacking in some confidence, the Touroll J1 Step Through glided me into my first ride with a steady but power driven start.
After a couple of mini rides on the road, I ventured out on a cross country ride along narrow paths and over gravel roads, before heading back via a cycle route alongside the road, up a steep hill and all the way home.
It was an exhilarating ride. The Touroll J1 transversed the uneven narrow paths and gravel road with ease.
I used the power mode to drive through areas that may otherwise have halted the journey, but the extra power helped me breeze through these obstacles.
On the journey back, I ramped the power up to the maximum and was given a thrilling ride home. When reaching the big hill at the end of the journey, which normally would leave me puffed out and struggling to manage in one go, the extra power from this fabulous electric bike, gave me what I needed to enjoy the hill ride all the way. I did over 25km in total and still have 79% left on the battery.
It really was the most fun I have ever had. I went further than I've been for a long time and got to enjoy the scenery around me without feeling like my legs and lungs were about to burst.
I absolutely love this bike and would recommend it to anyone thinking about a very decently priced electric bike as their first ebike experience. Amazing value for money - thanks to PDB.
I am really happy with my Touroll J1 electric bike overall . There could have been an improvement if it had 21gears instead of seven gears but overall it is great !!
Love this bike. It’s cheap compared to most ebikes but it does the job and the pedal assist works really well and the bike looks great.
Brilliant bike really comfortable enjoyable rides to work also the company is brilliant a must for anybody the bikes are 5 star ian is brilliant
Arrived in good time, easy install and does the job of making the riding position more comfortable and upright, Dutch style.
First e-bike I’ve ever owned great gears excellent brakes front suspension is comfortable seat is alright and a large battery, it comes with a slow charger. Unfortunately it doesn’t stop charging I suppose when it’s full the current bounce back to the charger I don’t really know. I easily find cheap mud guards on as it’s designed with the option of mud guards.
Now the negatives are it’s a 29 inch frame so it’s very heavy, the power doesn’t always kick in early, the chrome screw bolts are already rusty however I don’t think it will degrade in the near future. That’s about all I can think of the negatives. I love this bike and to me it’s worth the money, it also comes with the stand bar and adjustable seat height front head light. Best of all this website PDB has excellent customer service
Is the Zebra and big dog the same battery because I will like to share the battery with my wife. She have the zebra and I’ll like to buy big dog?
Many thanks
I’ve this version 2020 but, how can I get the throttle speed limit on?
I bought the Cruiser but will buy it for my daughter next week.
I’ve seen the zebra battery is way bigger then the cruiser,
What a great Electric Bike, quality is the best if long range I do 95 miles one charge…..,
I loved it this e-bike, the range is amazing with pedal assist I do 80miles and now the US controller is available in EU & UK , it Unlocked the Throttle. 🥰
Very pleased 😀 thank you
As a new entrant to the ebike market I did some research and found the M1 Plus.
Having only experienced more expensive ebikes on holiday in Europe I was really impressed with this bike.
You can't feel the power as much on the lower settings but for getting around it's great.
Delivery was quick. the battery's not great but doesn't need to be. The gears aren't aligned properly and I can't get them to be. The discs rub. But for a £600 ebike it's great.
