I'm in the Haibike forum and not the Riese and Muller forum? Yes, I ordered a Haibike as my backup commuter and alternative ride. I wanted to switch things up from time to time and have a backup bike for when the R&M needs work. Several factors influenced my purchase decision in no particular order: felt like a class 1 wouldn't slow my commute too much due to all the start/stop I have wanted to stick with Bosch for availability of service and battery sharing wanted a lower tech bike as the backup (no IGH and not a belt drive) for better availability of mechanics that can fix things most important: wanted to buy locally this time since I am not a good mechanic and am dependent on local shops for service - for mid-tier to upper-tier Bosch bikes this means I only had access to Trek and Haibike (could buy Specialized Vado if I wanted a Brose bike) Rode the Trek Super Commuter but don't like the red color and lack of suspension Really like the motor and battery integration on the Trekking 4.0; how the CX motor is tilted up, also like the lighting on the 4.0 Pleased with the Super Moto-X tires on the R&M and same come on the Trekking 4.0; originally thought to go to a narrower tire but my roads really suck; and I've run over a lot of glass with my Moto-X tires and so far no flats The biggest concern was sizing and there are some posts in this thread about that: https://electricbikereview.com/forum/threads/are-haibikes-huge.13377/page-2 Trying the bike for sizing wasn't going to be an option unless I was willing to travel. I spent quite a bit of money doing this when I purchased the R&M and didn't really want to repeat with this purchase. So sizing was the biggest concern/risk with this purchase. I had several knowledgeable opinions steering me to the S 52cm and several to the XS 48cm frame (I'm 5'8" to 5'9" and 29.5" inseam - buy 30" inseam jeans). I ordered the XS as the opinions and feedback on this forum seemed to tick slightly in the favor of the XS. But the real clincher was the shop telling me they would put the bike into inventory if it wasn't the right size and order another for me. Great service from the shop which is primarily a Trek dealer but also sells IZip. They are a local outfit with a few locations and one of their locations has sold some Haibikes. My location has never stocked one so they had to do some research on order process etc. But they seem to think the bike will be one they can sell to another customer if it doesn't fit me. That really reduced my risk of purchase. I even offered to pay a restocking fee if necessary but they cited me being a good customer etc and said that wouldn't be necessary. We also compared the Trekking 4.0 specs to some Treks and it seemed to fit more closely to the Powerfly 5 which they had in the shop. I took out a 17.5" Powerfly 5 (really fun bike by the way) and it seemed a good fit. Standover height on the Powerfly was listed the same as the Trekking 4.0 for instance. Geometries after that varied somewhat but fingers crossed that the 17.5" Powerfly was close enough of a proxy to the XS Trekking 4.0. So when the bike comes in and if it fits I plan to make some mods (BodyFloat, maybe pedals, maybe handlebars, locking seat clamp maybe some security skewers), find some fitting panniers and/or trunk bag, and then break the bike in for some later summer commuting. I hope to have some feedback and comparisons to the R&M Charger to post here in the near future.
