Bristol’s Biggest Hills on an e-bike

Bristol’s Biggest Hills on an e-bike

One of the first things people want to know about an electric bike is how it feels on a hill. What is the assistance like? Will I be able to get up any climb? How easy will it make the ups?

At our Nailsworth showroom, we’re lucky to have a beast of a hill on our doorstep, so when people demo our e-bikes, they quickly find out how satisfying going up big hills can be on these machines.

E-bikes are popular for commutes because they eat up the hills, so you can arrive at your workplace fresher, full of endorphins and significantly less sweaty!

 Encouragingly, The number of cyclist commuters in our home city of Bristol has grown enormously in the past few years, and it’s a city with no shortage of hills.

With that in mind, we decided to take 2 of our most popular urban e-bikes and tackle five of Bristol’s biggest climbs. Who better to do this than Dan and Rufus?!

What bikes did they ride?

Riese & Müller UBN Five Silent Selva

Dan rode the Riese and Muller UBN Five, which comes with the Fazua Ride 60 drive system, provides 60Nm of torque (torque the power you need for significant inclines) and is equipped with a 430 Wh battery. Dan’s bike was the Silent specification with a Shimano Alfine 8-speed hub gear.


Rufus rode the Riese and Muller Roadster, equipped with the Bosch Performance Line CX motor that provides 85Nm of torque and is powered by a 625 Wh battery. The version in the video is the Roadster Touring which has an 11-speed derailleur gear.

Which hills did they tackle?

  1. Whiteladies Road
  2. Park Street
  3. Constitution Hill
  4. St. Michael’s Hill
  5. Vale Street

Whiteladies Road

They started gently with the 6%(ish) Whiteladies road heading up to Downs. Dan rode the UBN Five without motor aid for much of the climb, only turning on the lowest level of assistance with the Fazua (Breeze) for the steeper end to the ascent, but he did get into the lowest gear on the Shimano Alfine 8-Speed hub. The ‘Silent’ specification with the Alfine Hub gives a beautifully quiet and smooth ride. The Fazua motor is certainly less noticeable in appearance than the more bulky (and more powerful) Bosch motor on the Roaster. If you’re looking for quiet and inconspicuous, the UBN wins but at a performance cost.

5 of Bristol's climbs

Park Street

One of the more well know hills in Bristol, Park Street starts at College Green and ascends, peaking at roughly 10% gradient. Dan kept the UBN in Breeze (or equivalent Eco on the Roadster with the Bosch motor) for the ascent and made it to the top with quite a lot of effort. He could have upped the assistance if he wasn’t holding the GoPro the whole way up! Meanwhile, Rufus cruised in the second level of assistance (Touring) on the Roadster and arrived in good shape.

Constitution Hill 

A much more threatening-looking hill at a 16% gradient, Constitution Hill provided more of a challenge and highlighted some differences between the two bikes. Dan rode up the lowest gear and in Rocket mode, and although he comfortably made it to the summit, he was definitely out of breath. At this point, Dan became suspicious, noticing Rufus was barely exerting himself, so they agreed to do the same climb but switch bikes, so Dan was now riding the Riese and Muller Roadster with the Bosch motor. Dan isn’t as unfit as he thought; he and Rufus noticed the extra power that the Bosch motor in the Roadster provided and found Constitution Hill considerably easier. The Roadster also has an 11-speed cassette versus the Shimano Elfine 8-speed hub giving a bit more oomph on the steeper hills.

St. Michaels Hill

Back on the UBN, this hill provided little challenge to Dan, although he did find that more gears and more torque enabled Rufus to power away a little; overall, the Fazua motor ate up this sort of gradient. The next hill, Vale Street, was a different matter. 

Vale Street

At 25% gradient, this was a good challenge but perfectly achievable on either bike and multiple times, as Dan did in the name of proper testing. Using the Fazua motor’s boost mode (on the UBN) gives a few seconds of full torque to get up the steepest part. However, Dan’s preferred ride on hills like this was the Roadster with the Bosch motor and 11-speed derailleur. There’s a gentle whirring sound, but he found the extra power made a big difference and enabled him to enjoy the hill much more.

Riese and Muller UBN5 vs Roadster

Bosch performance line cx vs Fazua Ride 60

If you are looking for a bike that can eat up the biggest urban hills then the Roadster’s higher torque Bosch motor will provide a more enjoyable climb. Furthermore, if the range is a concern, the larger 625Wh battery on the Roadster will also be a strong plus. However, the quieter and sleeker UBN is a fantastic bike if you commute with moderate or minimal hills.

The UBN Silent uses a Gates Carbon drive with the Shimano Alfine hub, an excellent setup for low/no maintenance commuting. There’s no messing around with oiling your chain and then getting oil on your work trousers! Furthermore, you won’t need to spend time indexing your gears and maintaining the derailleur. If this appeals, but a higher power motor and a larger battery are desired, it’s worth considering the Roadster specified with the Vario hub.

Upgrade Your Commute: Come and give one a try.

We can’t extol the virtues of an e-bike for commutes enough. Those mornings when you’re unsure if it’d be easier to get in the car become a thing of the past, and that feeling like it’s a few miles too far to do twice a day – is gone. 

Book a test ride at our showroom in Nailsworth or Bristol and upgrade come and see how you can upgrade your commute.

I came across these guys as I couldn't find a stockist in Scotland who did the bike I was looking for. From the get go the staff were really helpful, I mostly dealt with Jen, they didn't bat an eyelid at my many requests and changes including delivery to central Scotland - working around my timescales. Brilliant service!

Lots of good advice, no pressure and plenty of opportunity to road test bikes. I was on a break in Glos and called in to EDEMO, having previously watched a number of their very useful you tube videos about Riese & Muller bikes. Two days later my chosen stock bike was prepared and paid for and a week later delivered to my address in Cumbria. Faultless. A pleasure dealing with them. The bike is great too!I would recommend.Thank you

Excellent service. Dan guided me through all the choices, Jen organised the delivery and kept me updated, and AJ delivered the bike and got me set up and going. The team let me know I can come back to them anytime for any help or support I might need.

I had a test ride booked and was pointed to a very steep hill to try the bike on and then a reasonably flat cycle-way to give me an idea of different riding scenarios. Enjoyable test ride. Got back to the shop and had a talk about the bikes and tried a different model. I got some very helpful advice, decided on the bike and purchased it. They delivered the bike to my home and spent some time running through all the features and adjustments I could make. Very happy with the bike and the service from Edemo.

It was such a pleasure to buy my bike from Edemo after years of dealing only with internet based suppliers. I used the Bristol based office/workshop and enjoyed the entirely personal service provided by AJ who also delivered my bike to me when it was ready and explained how to operate and maintain it. In particular I felt reassured that Edemo would continue to provide support during my ownership of the bike. Great service throughout!

Dan and the team at EDEMO were super helpful in getting my new bike sorted. We found them really knowledgeable, and honest in how they helped me choose; finding something that would be exactly suited to what I needed, not just the most expensive option in the shop. The process of trying out bikes and chatting through everything was enjoyable. For me, the Riese & Muller range that they stock encompassed great options. Using only one supplier did make the process more straightforward than at other places as EDEMO could provide a wider range of options rather than just having lots of very similar bikes from different suppliers. Dan was helpful in organising what we needed so we could use the cycle-to-work scheme. The pick up process was thorough and thoughtful, making sure I had everything I needed and knew all the ins and outs of the bike.

A top team! Really know their products, are willing to invest the time in helping you understand them as well. One of the best sales and service experiences I’ve ever gone through! Now bought two bikes from them! Just cannot fault any aspect of their service delivery.
Another 5* review from me.If you were on the fence of spending the extra £££ on a R&M, visit the shop and test ride one of their bikes. They seem to have most, if not all their models in store.Very friendly service too :).

Excellent purchase process with no pressure. Edemo were patient and happy that I wanted to try many different makes of cargo bike before deciding which one to purchase.. In my view, for my needs, the R and M Load 75 was superior in all respects. Since purchase the bike has exceeded my expectations

We received absolutely brilliant customer service from Edemo. They all have really in depth knoweldge about the different bikes so could answer any question. We could test ride any bike we wanted which is so important. They were really accomodating with our Bike to Work scheme. When we bought the bike it was delivered with a really in depth handover, and after sales support is very helpful. Can't fault them!

Very helpful staff in the Nailsworth shop (even though I came on the wrong day)Was able to try three different models and different setups which was invaluable and meant making the right choice of bike was easy.The R and M website is good but being able to try and chat about the various models and options made sense of it all. The Edemo website is also extremely helpful.Ordering was very easy and delivery happened when they said it would. When the bike was delivered it was all set up with a couple of small adjustments done on the spot.I would happily recommend Edemo to anyone.

A really excellent service, especially from the workshop team who had no problem ordering extra parts from Germany and helping me make changes to the Multicharger I bought from them.I would highly recommend Edemo to anyone looking to purchase a Riese and Muller Ebike. With so many things in life the back-up and after sales service is key, especially with an investment such as one of these excellent bikes.

All worked well and am happy with the bike as well as the support from Dan's team. There is quite a lot to learn because the bike is a step up from previous electric bike that I have had but the result is very good and I am still learning.

Excellent all round buying experience. Dan was really helpful going through options no hard sell or pressure too buy. We visited his shop twice and test rode any of the bikes as many times as we liked. Nailsworth has good test ride conditions and good lunch stop for a nice day out. We bought 2 charger 4’s didn’t really want to spend that much money but they are already paying back as the car is parked up for many of our trips a 20 mile trip is quite easy now, we live rural with big hills. Bikes took about 3 months to come so if your thinking about it get your order in. They were delivered by AJ who gave us a good briefing. If you want a R &M get it here if your no sure go test ride one.
