Paul,some of the Kudos employees do a 25 mile round trip to work on either a KTM Revelator Elite or Kudos Rapide. Interestingly they do the 12 miles in about 40 mins,irrelevant whether using the non assisted or assisted bike,however when using the KTM they do need a shower before work.
The journey is probably average terrain,some hills but mainly on the flat,they are young 40's but very fit. The Kudos always has spare battery capacity but they are able to charge at work.
I personally,and several others think the Kudos Sonata,the most comfortable riding stance....the Sonata has a unisex appearance and that old chestnut .....'step thru is a ladies bike' seems to be almost finished.
I strongly suggest that you try a step thru for daily commuting,the slightly more upright riding stance is easier on the back and the vision is better.
The Kudos Sonata at its price level is quite a unique bike,it has the BPM motor,Tektro hydraulic brakes,Deore gears,Samsung slimline battery,yet it gets ignored on Pedelecs members radar....the KTM Macina Bold offers similar spec but at a considerable price increase.
Both the Sonata and Rapide are available for testing at Kudos warehouse in Kent or the London Electric Bike Company in Hampton Wick,West London.
You posting headed 'trying bikes' but the options to try are diminishing,nobody on this forum reported that they attended the London Bike Show to test e-bikes. The last 2 Redbridge events were poorly attended and the green fairs/ gadget shows all reported lack of serious interest. It seems that some dealers like On-Bike,LEBC,50 Cycles....who have good stocks of demo bikes are the best bet to try a number of bikes.
There was recently a posting from a forum member who one day said he knew nothing about e-bikes and next day bought a bike cheap off the Internet without testing any bikes at all. I find that very strange (suspiciously strange!!!!!),we so often get a bike ready for someone who is adamant he knows exactly what he wants and after testing buys a completely different bike. Buying a bike without riding one is like getting married to a girl( or guy) you have never met,so often ends in divorce and painful on the way....hehe
