In the Cons where you were comparing drive system you wrote “from Bosch and Shimano”, did you mean something else? CheersReply

Ahh, great catch there Anthony! I meant Bosch and Yamaha, thank you… just put in a fix and it should appear once the cache clears. Appreciate your feedback :)Reply

I have been using this bike as my daily commuter (40 miles a day) for a couple of weeks. Changed the seat post to a suspension post, the saddle, and the pedals. So far I’m pretty happy with the bike and the Shimano Steps system. Electronic shifting works well but you do get the occasional ratcheting noise from the hub. This is quickly sorted if you stop pedaling for a second. Auto-shift is great on good pavement, on cobblestones and very short inclines it sometimes misses to choose the correct gear. It’s best to resort to manual in these circumstances.
One point of concern is the Shimano chain tensioner. This is not a spring tensioner and needs to be adjusted manually. I managed to pull the chain off the rear sprocket twice because the chain tension wasn’t tight enough. If the chain is too loose it will derail on bumpy pavement.
You should also get the Shimano tool (TL-EW02) to disconnect and connect the electric cable to the shift motor. The cable is very frail and as Shimano states in the manual is not meant to be disconnected frequently. A shame Walleräng doesn’t include the tool with the bike.Reply

Hi BUD, you’ve brought up several important points. This is exactly the sort of feedback that I don’t get with my limited tests so THANK YOU for recommending the tool, talking about performance on cobblestones and mentioning the chain tensioner. I’m sure this will help others to learn how to better ride the bike and maintain it and might even reach Shimano to guide future product development. I hope the Walleräng holds up well for you in the future, feel free to share other updates as you continue to ride :)Reply

At this time I would like to update my review of the Walleräng. In my first post I mentioned the problems I experienced with the chain derailing. These problems persisted, on average this happened twice a week. Not ideal for a bike bought for your daily commute… I contacted Walleräng directly to get this problem fixed. At first they send a replacement chain tensioner to the dealer, the dealer also checked if the chain line was properly aligned. Unfortunately this didn’t solve the problem, the frequent derailing of the chain wasn’t fixed. I noticed that the original chain tensioner (Shimano CT S-510) failed to maintain the proper chain tension, maybe caused by the sudden torque of the motor. When the chain is too loose it will derail very easily.
Securing the adjustment bolt with strong LocTite helped to reduce the frequency of the breakdowns a bit but wasn’t a permanent fix. Walleräng acknowledged the problem and proposed to replace the chain tensioner with a Shimano CT S-500 tensioner. This is a spring chain tensioner and it absorbs the chain slap without losing proper tension. It took a lot of e mails and several months(!) of patience but Walleräng sent the chain tensioner, a new dropout to mount the new tensioner and the CT S-500 to the bike shop and the problem is finally sorted. I have been using the bike with the new tensioner for a couple of weeks now and the chain hasn’t derailed once.
Also a word on the auto shifting functions of the Di2 system. I have completely stopped using auto shift since it is very harsh on the Alfine gear hub. I now change gears manually and even stop pedaling while shifting. The Alfine shifts a lot better (and quieter) when there’s no pressure on the pedals. For that reason I also disabled the auto downshift function at standstill, with auto downshift engaged the hub sometimes seemed to be in between two gears when riding off. The only drawback on manual shifting to me is that the shift buttons are too small, especially when wearing winter gloves. A trigger system would be a lot better than these small buttons.
The Walleräng, like any bike, has its flaws and its strong points. However, based on my experience, the M.01 with the original CT S-510 chain tensioner is not recommended. In fact, I would walk away from any E bike that uses this chain tensioner.Reply

Thanks for your thorough feedback Bud! I’m glad you were able to get help, adjust how you ride the bike to minimize failure, and share all of this valuable information with me and other owners or prospective buyers. Hope the bike can hold up for your commute, share updates any time.Reply

Does anyone know if baby seats fit on the rack? if so, which ones?Reply
Court4 years ago
Hi MMM, I think it’s likely that the Thule Yepp! Maxi will fit into the square “windows” of this rack, and very likely that the newer Yepp! Next (that clamps on the sides) would work here, but you might want to call the company or a dealer to confirm.Reply
