Strong, blinking and "ultra-annoying" lights are more efficient than a flag i would say
Im using ones from ebikes.ca - they rock!
I am not an expert, not even ridden a trike in my life but for off-road riding i hear that it is better to have weight more in front / front central of the trike. Also it is not good to have a 12kg of unsuspended rear wheel for off-road cycling. That is what experienced people here told me!
But it does not contradict with the fact that heavy rear will improve the traction!
Btw i was close to get steini [another things many people here stressed a lot - to get a fully for offroad triking] but with all the extras i would want to have and customising to my needs and likings, i would need to spend well over 4000 eur. So i had to postpone the purchase.
But just very recently i talked with Kamil from Velokraft. He is now working on a rickshaw project and said he could use his unique suspension from this rickshaw in an offroad recument trike. [if it passes the testing] So in the end he agreed to build a trike for me! I'm sooo excited about it! I dont know any details but in May, if all goes well - i will show you the pics / videos!
Are you from Quebec city? My wife is from there
