Hey, is anyone of you using the Alpenchallenge AMP SPORT TWO? A local dealer offers the bike with a 20% discount, but I'm not completely sold on this version, because it's a bit heavier than the carbon models and only offers a 418 Wh battery.
And I'm also not sure about the overall look of the Alpenchallenge Amp bikes. I have an Orbea Gain F40 with a small integrated battery which does not scream E-Bike at first look
. But I absolutely fell in love with the power of the Shimano Steps motor and the quality of the BMC bikes in general. Another powerful alternative may be the Cannondale Synapse / Quick Neo, which offer an integrated battery, but are heavier than the BMC AMP models (about 18 kg).
A quick shot of the test bike (may look a bit weird because of iPhone ultra wide lens):

Hello there, Well im going try to give you my opinion and then you take your own conclusions.
1. Its quite obvious the alumium version is going to be heavier than the carbon, but as well is cheaper, you should ask yourself if you are eager to take the extra expense in the carbon version.
2. About the external battery screaming out is an e-bike, well, the most important purchase desition is if you like or not, if you dont like it then theres not much to discuss. But on the other side is important you to know why this decision was taken ( and this info was told to me directly not only by BMC people but by Diamant german bikes who is a competitor company, so its not that they tried to look good to me):
At the moment With the current technology, all the bikes that has an internal battery require a thicker tube either in size and the thickness of the metal itself because of the cutout for the battery. So they need this extra material/weight in order to make it sturdier in this area.
I can corroborate this info as well putting as example my girlfriends bike:
Small sizes, massive possibilities Our premium compact E-commuter brings first class comfort and a limousine feel to a wider range of riders than ever before. Let the almost silent Shimano motor take the strain on hills so you arrive fresh. Know that we’ve perfected the handling balance of the...

its a relatively “cheap” not fancy (to be electric) bike, but the fact that has external battery make it ”only” around 18kg.
But if you check all the other bikes with internal batteries they are heavy, this incluides the Diamant Supreme plus, which is carbon fibre but it weights 22.5kg, is not the only reasson obviously but i guess you understand what i mean.
Diamant Zouma Supreme+ ✓ Pedelec bis 25 km/h ✓ Klassischer Herrenrahmen ✓ Diamant: Passion fürs Rad seit 1885.

The only bike at the moment that i know with internal battery that are very light are the new Specialized Turbo Vado SL.
They are light for a lot of reassons (weaker engine, etc), but lets focus on the battery; since the battery is smaller it obviously weight less, and (very important) you cannot pull out the battery, you have to charge it directly with the bike, in this way they saved crucial weight avoiding the cutout, its like old times of mobile phones with removable battery and iphone with not removable battery (to save weight and space). And the other one I guess would be your Orbea who follows a similar design solution.
having said this, now maybe you understand why BMC has decided to use this design.
3. Regarding the price, i recommend you to look everywhere online:
bike24, tredz and so on offers BMC Bikes, check and compare and you can do a better decision.
4. About the engine, so as mentioned before, my girlfriend has a whyte bike with the steps 6100, i have the City LTD with the shimano 8000, its obvious that the 8000 has more power, but you have to ask yourself do you need the extra power? We live in Edinburgh a very hilly city and she has more than enought with the 6100, i would say the 8000 helps mainly if i would take it to the mountain, or (ironic) if we challenge each other for some race, the bike power will cut at 25km/h anyway.
5. On an extra note, you have to decide how important is the weight for you, we live in a first floor apartment (its called second floor in some countries), so we carry our bikes trogh the stairs, i made some changes in my girlfriends bike to save weight: Tubus titanium rack, XTR cassette, carbon fibre seatpost, specialized MIMIC carbon fibre saddle, her tires and wheels were tubeless ready so i just converted it saving extra 400grams.
So now her bike is around 17.2 kg.
If you dont have this problems then go simply for whatever you like the most.
Hope this answer helps.
